Solution

The correct option is D 1200 J
Answer is D.

The potential difference is the electrical energy change per unit charge. So the electrical energy change for 100 C is given as follows.
12 V * 100 C = 1200 J (1 V = 1 J/C)
Hence, 1200 J of electrical energy is converted to other forms of energy in the conductor when 100 C of charge flows through it.
