Watt’s Law Formula
The following formula is used to calculate the power using Watt’s law.
P = V * I
- Where P is the power (watts)
- V is the voltage (Volts)
- I is the current (amps)
To calculate power using watt’s law, multiply the voltage by the current.
Watt’s Law Definition
Watt’s law describes the relationship between power, voltage, and current. This law states that power is equal to the product of voltage and current.
Watt’s Law Example
How to calculate power using watt’s law?
- First, determine the voltage.
Measure the total voltage of the circuit.
- Next, determine the current.
Measure the current of the circuit.
- Finally, calculate the power.
Using watt’s law calculate the electrical power.
