Enter your voltage, current, and resistance into the calculator to determine your power.
VI Calculation Formula
The following formula is used to calculate the power from your voltage and current.
Power (P) = Voltage (V) * Current (I)
Variables:
- Power (P) is the power in watts (W)
- Voltage (V) is the electrical potential difference in volts (V)
- Current (I) is the electrical current in amperes (A)
To calculate the power, multiply the voltage by the current.
What is VI Calculation?
VI calculation refers to the process of determining the power in an electrical circuit based on the voltage and current.
