Electric Power Formula
Physics is the natural science that investigates matter,[a] its fundamental elements, motion and behaviour in space and time, and the linked concepts of energy and force. Physics is one of the most fundamental scientific fields, with the main purpose of understanding how the universe acts. A physicist is a scientist who specialises in the discipline of physics.
As students are probably aware, electric power is a commonly used phrase in physics. It is also important because it allows us to see how quickly electrical energy travels from an electric circuit. As a consequence, it assists us in assessing its efficacy. The Electric Power Formula may be defined as the pace at which work is completed. P represents the SI unit of power, watt. The power formula is connected with time, voltage, and charge. Individuals can modify the formula by applying Ohm’s law.
The Electric Power Formula for power is as follows:
The Electric Power Formula P = VI
The Electric Power Formula written in terms of Ohm’s law is P = I2R = V2R
Definition
Electric power, like mechanical power, is a measure of how quickly work is completed. In our nation, though, it is measured in watts. Furthermore, wattage is a colloquial word for electric power measured in watts.
Students have probably seen electric power generated by generators and other sources such as electric batteries. Furthermore, businesses and houses frequently acquire this supply from the power sector via an electric power grid. Following that, power is measured by electric utilities using an electricity metre, which keeps a running total of the electric energy provided to a consumer.
Electrical power provides energy with low entropy. It may also be carried across long distances. It may also be converted to other types of energy like light, motion, or heat.
Electric Power Formula
Electric power is defined as the rate at which energy is moved to or from an electric circuit component. Energy can be supplied by a battery or a circuit component, such as a resistor that releases energy as heat. Any circuit element’s power is equal to the voltage differential across the element multiplied by the current. Looking at it through the lens of Ohm’s Law, we can see that V = IR in this case, meaning that there are many forms of the Electric Power Formula for resistors. Watts are the power measuring units.
Furthermore, it is critical to comprehend that a Watt Equals Joule per second. (1 W = 1 J/s).
Therefore:
P = VI
here,
The electric power refers to P
The voltage difference is v
The electric current is I
Then there’s the resistor formula, which combines Ohm’s law with Joule’s law. As a result, we have
P = I2R = V2R
Over here:
the electric power (W) is P
the difference in voltage (V= J/C) refers to V
the electric current (A = C/s) is I
the resistance (Ω = V/A) is R
