The potential difference across a resistor is 12 V. The current in the resistor is 2.0 A. A charge of 4.0 C passes through the resistor. What is the energy transferred in the resistor and the time taken for the charge to pass through the resistor?
Aenergy/J: 3.0, time/s: 2.0
Benergy/J: 3.0, time/s: 8.0
Cenergy/J: 48, time/s: 2.0
Denergy/J: 48, time/s: 8.0
✓ Correct answer
C: energy/J: 48, time/s: 2.0
