Current Calculation
According to Ohm’s law, current is calculated.
The voltage V in volts (V) divided by the resistance R in ohms (Ω) gives the current I in amps (A)
Solved Example
The potential difference across a 24 Ω resistor is 12 volts. What current is flowing through the resistor?
Solution
V = 12 V
R = 24 Ω
Current, I =?
Based on Ohm’s law,
I = V/R
I = 12/24
I = 0.5 A
