Current through a 6 Ω load on 12 V

Answer: current = 2 A (power 24 W).

What we know

  • Voltage: 12 V
  • Resistance: 6 Ω

Step by step

Given
V = 12 V, R = 6 Ω
Formula
I = V / R
Substitute
I = 12 / 6
Result
I = 2 A

All results

Current2 A
Power24 W

The physics

Ohm's law says current through a conductor is voltage divided by resistance. Voltage is the electrical 'pressure', resistance the narrowness of the pipe, and current the resulting flow.
