Welcome! This page will assist you in calculating power in a circuit by inputting values for voltage and current.
This can either calculate the total power in a circuit or the power dissipation of particular electrical components.
Calculation
Inputs


Voltage
:10volts​



Current
:10ampere​

Output


Power
:100watts​


Explanation
Power is the rate of electrical energy transfer per unit of time. It is a fundamental principle in electrical analysis.

P=VI
Where:

P=Power (W)V=Voltage(V)I=Current(A)
👉 Important information
When analysing AC circuits, it is important to note that sinusoidal power sources, components such as inductors or capacitors, and non-linear devices can drastically affect circuit analysis.
