Question

1(a) Lightning Flash

A lightning flash may transfer up to 18 C of charge through a potential difference of 107 V. How much energy does this involve?

Answer 1

The energy dissipated by the lightning flash is 1926 joules.

Step-by-step explanation:

To calculate the energy dissipated by a lightning bolt, we can use the formula: Energy = Charge x Potential difference.

Given that the lightning flash transfers 18 C of charge through a potential difference of 107 V, we can substitute these values into the formula:

1. Energy = 18 C x 107 V
2. Energy = 1926 J

Therefore, the lightning flash involves 1926 joules of energy.
