Ohm Law in Computer Circuits
Calculate voltage and electrical power in basic circuits.
V = I × R; P = V × I
Formula Explanation
Ohm law relates voltage, current and resistance; electrical power equals voltage multiplied by current.
Variables Explained
V = Voltage; I = Current; R = Resistance; P = Power.
Solved Example
A circuit has 5 V and draws 2 A. Find power.
P = 5 × 2 = 10 W.
