The electrical power in the circuit is the product of potential difference across the circuit and the current transmitted through the circuit.
![\bold{Power = Voltage\ difference * Current,\\ P = V * I}](https://img.qammunity.org/2020/formulas/physics/middle-school/57ygnbr11ga2uztvgbspss7lrg5a5sh6g9.png)
Step-by-step explanation:
This has been derived from the ohm’s law which can be further derived in terms of current and resistance or potential difference and resistance by simply input the value of either current or potential difference from ohm’s law.
Ohm’s law:
