The resistance of the wire is given as 1.2 ohms. To find the potential difference, we first need to find the current using the charge (Q) and the time (t), with the formula I = Q/t. Here, Q = 150 C and t = 15 s, so I = 150 C / 15 s = 10 A. Then, using Ohm's law (V = IR), where I = 10 A and R = 1.2 ohms, the potential difference V = 10 A * 1.2 ohms = 12 V.
