If you have ever looked at your laptop, remote control, or car dashboard, you have seen the power symbol without even thinking about it. That small circle with a line through it sits on almost every electronic device we own. But this simple icon carries a surprising amount of history, meaning, and variety.
In this guide, we will walk through every major type of power symbol you might be searching for. This includes the standard on off icon, the mathematical exponent sign, electrical and circuit symbols, spiritual power signs, and even power symbols from pop culture like Pokemon and EXO. You will also find a full copy and paste list at the end, so you can grab any symbol instantly.
What Is A Power Symbol?
A power symbol is any sign or icon used to represent power, energy, strength, or the act of turning something on or off. The meaning changes depending on where you see it.
- On electronics, it usually means on, off, or standby ๐
- In math, it represents an exponent or repeated multiplication โ๏ธ
- In spirituality, it represents inner strength or protection ๐
- In pop culture, it can represent a fictional ability or fandom logo ๐ฎ

Power Symbol Meaning
The most common power symbol is a circle with a vertical line breaking through the top, written as โป. This icon comes from the International Electrotechnical Commission, or IEC, and it is meant to represent a binary switch. The circle stands for 0, and the line stands for 1, since early electronics used binary numbers to represent off and on states.
There are actually several official variations, not just one:
| Symbol | Name | Common Meaning |
|---|---|---|
| โป | Power symbol | Standby or general power button |
| โผ | Power on off symbol | Toggles between fully on and fully off |
| โฝ | Power on symbol | Device is on |
| โญ | Heavy circle | Device is off |
| โพ | Power sleep symbol | Sleep or low power mode |
Power Symbol History
The power symbol was not always standardized. Before the 1970s, manufacturers used the words “on” and “off” printed directly on switches. As electronics became global products, companies needed a symbol that worked regardless of language.
The IEC introduced standard 60417 to unify these icons across the industry. Later, in 2015, a campaign led by technologist Terence Eden pushed for these symbols to be added to Unicode so they could be typed as text rather than only used as printed icons. The request was accepted, and the power symbols officially became part of Unicode version 9.0 in 2016. This is why you can now copy and paste them like any other character today.
Power Symbol And Strength
Beyond electronics, the word power is closely tied to the idea of strength, resilience, and control. Many cultures created their own visual language to represent this concept long before electricity existed.
Symbols associated with strength usually share a few visual traits:
- Bold geometric shapes such as circles or triangles ๐บ
- Animal imagery like lions, bulls, or eagles ๐ฆ
- Sun and fire motifs representing energy ๐ฅ
- Fists or raised arms representing willpower ๐ช
These symbols are often used today in tattoos, logos, jewelry, and motivational artwork because they carry meaning at a glance without needing any text.
Power Symbol In Math
In mathematics, the power symbol refers to an exponent, which shows how many times a number is multiplied by itself. For example, in the expression 2ยณ, the number 2 is called the base and the small raised 3 is called the exponent or power.
This is read as “2 raised to the power of 3,” and it equals 2 ร 2 ร 2, which is 8.
A few quick facts about the math power symbol:
- The caret symbol (^) is used to represent powers when typing, since superscript is not always available on a keyboard ๐งฎ
- An exponent of 2 is commonly called “squared” โ
- An exponent of 3 is commonly called “cubed” โ
- A negative exponent means the value becomes a fraction, such as aโปยน equaling 1 divided by a ๐
Common Power Notations In Math
| Expression | Meaning | Result |
|---|---|---|
| 5ยฒ | 5 squared | 25 |
| 2ยณ | 2 cubed | 8 |
| 10โด | 10 to the power of 4 | 10000 |
| 4^(1/2) | Square root of 4 | 2 |
Power Symbol In Physics
In physics, power is a measurable quantity, not just a symbol on a keyboard. It refers to the rate at which energy is transferred or converted, and it is represented by the capital letter P in formulas.
The standard formula is written as P = W / t, where W is work done and t is time. Power is measured in watts, named after inventor James Watt.
Key physics facts worth knowing:
- One watt equals one joule of energy transferred per second โก
- Electrical power is often calculated using P = V ร I, where V is voltage and I is current ๐
- Mechanical power can be calculated using force multiplied by velocity ๐๏ธ
- Kilowatts and megawatts are used for larger scale power measurements ๐ญ
Electrical Power Symbols
Electrical diagrams rely on a standardized set of icons so that engineers anywhere in the world can read the same schematic without confusion. These symbols are grouped under IEC and ANSI standards.
| Symbol Name | Appearance | Used For |
|---|---|---|
| Power supply | Rectangle with plus and minus | Marking DC voltage sources |
| Ground symbol | Downward pointing lines | Showing electrical grounding |
| Fuse symbol | Rectangle with a line through it | Circuit protection |
| Battery symbol | Long and short parallel lines | Representing a power cell |
| Transformer symbol | Two coils with core lines | Voltage conversion |
These symbols allow anyone reading a wiring diagram to instantly know how current is meant to flow through a system.
Power Symbol In Circuit Diagrams
In circuit diagrams specifically, the power symbol usually marks the point where voltage enters the circuit. This is different from a ground symbol, which marks where the circuit returns to zero potential.
Common circuit power markings include:
- VCC, used to show positive supply voltage in digital circuits ๐
- VDD, commonly used in transistor level circuit design ๐ป
- GND, marking the ground or return path ๐ฝ
- A simple arrow pointing into the circuit, representing incoming power โก๏ธ
Circuit designers rely on consistency here, since a mislabeled power symbol can cause serious wiring mistakes during assembly.
Power Symbols On Off
The on and off power symbols are the most searched version of this icon because nearly every device uses them. Here is a simple breakdown of what each variation actually means.
| Icon | Unicode | Meaning |
|---|---|---|
| โป | U+23FB | Standby power button |
| โผ | U+23FC | Switches between full on and full off |
| โฝ | U+23FD | Indicates the device is currently on |
| โญ | U+2B58 | Indicates the device is fully off |
| โพ | U+23FE | Indicates sleep mode |
If you ever see the โป icon alone on a button, it usually means the device toggles into a low power standby state, not a complete shutdown.
Powerpoint Symbol
If you need to insert a power symbol into a Microsoft PowerPoint slide, you do not need any special software. Since these are Unicode characters, they can be added directly through the Insert menu.
Steps to add a power symbol in PowerPoint:
- Click on the Insert tab, then select Symbol ๐ฑ๏ธ
- In the font dropdown, choose a font that supports technical symbols, such as Segoe UI Symbol ๐ค
- Search using the character code 23FB for the standard power icon ๐
- Click Insert, then close the dialog box โ
You can also simply copy the symbol from this article and paste it directly into your slide using Ctrl V.
Power Symbols In KiCad
KiCad is a popular open source tool for designing printed circuit boards, and it comes with its own dedicated power symbol library. These symbols are different from Unicode characters since they are schematic components used specifically for simulation and PCB layout.
In KiCad, power symbols typically include:
- VCC and VDD symbols for positive supply rails ๐ง
- GND symbols in multiple styles depending on grounding type ๐
- Battery symbols for representing power sources in a schematic ๐
- Custom power flags used to tell the software that a net is externally powered ๐ฉ
Engineers use these symbols to ensure the software correctly checks for unconnected power pins during the electrical rules check process.
Fluid Power Symbol
Fluid power refers to systems that use pressurized liquid or gas to transmit energy, commonly seen in hydraulics and pneumatics. These systems have their own dedicated symbol language defined by ISO 1219.
Common fluid power symbols include:
- A circle with an arrow representing a pump ๐
- A rectangle with diagonal lines representing a cylinder ๐ฆ
- A triangle representing the direction of flow โถ๏ธ
- A square with internal markings representing a valve ๐ ๏ธ
These symbols allow technicians to read hydraulic and pneumatic schematics used in machinery, construction equipment, and industrial automation.
EXO Power Symbol
Fans of the K-pop group EXO often search for their official logo, sometimes referred to informally as their power symbol. The EXO emblem is a stylized letter mark rather than a literal power icon, but it has become a recognizable symbol of unity among fans, known as EXO-Ls.
The logo represents the group’s concept of members having unique powers in their early promotional storyline, where each member was tied to an elemental ability such as fire, light, or telekinesis.
Pokemon Power Symbol
In the Pokemon trading card game, certain cards feature energy symbols rather than a single power symbol. Each type of energy, such as fire, water, or electric, has its own icon that represents the power fueling a Pokemon’s attack.
Popular Pokemon energy types include:
- Fire energy, shown as a flame icon ๐ฅ
- Water energy, shown as a droplet icon ๐ง
- Electric energy, shown as a lightning bolt icon โก
- Psychic energy, shown as a swirl icon ๐
These icons function similarly to a power symbol since they indicate the source of strength behind an in game move.
