\[P=VI\]
Variables
Pelectric power (W)
Vvoltage (V)
Ielectric current (A)
Description
What is this formula?
This formula calculates the electrical power delivered or consumed in a direct current circuit.
When to use it
Use it when determining the energy transfer rate in DC electrical systems and electronic devices.
Example
Data:
V = 24 V
I = 3 A
Formula:
P = V*I
Substitution:
P = 24*3
Result:
P = 72 W
Applications
Electrical engineering, electronics, battery systems, power supplies, energy analysis, and circuit design.
