Lightning strikes can happen when there is a large potential difference between a cloud and the ground. The energy transferred during one lightning strike is 1.6 × 10⁰ J.A charge of 23.7 C moves between the cloud and the ground in a time t.The magnitude of the current is 3.09 × 104 A. Assume that the potential difference between the cloud and the ground is constant. Calculate t. Calculate the potential difference between the cloud and the ground. A power station has an electrical output of 1300 MW. Calculate the time taken for the power station to transfer 1.6 × 10⁰ J.
