Enter the voltage and current of an electrical system into the calculator to determine the power using watt’s law.
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)
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.
Watt’s law is a law of electro-magnetism that states that the power of a circuit is equal to the product of the voltage and current.
