Electrical power
Electrical power in a circuit is the energy that is absorbed or generated in the circuit. The symbol for electric power is
P
.
Definition of Power
The electrical power is calculated from the voltage multiplied by the current. The unit of measurement of electrical power is the Watt (
W
).
The dependency can be defined as:
By definition, the power P = 1 W when the voltage U = 1 V and the current = 1 A.
With Ohm's law (U = I · R), the formula for the electric power can be changed as follows:
