Problem 11-46 Current and potential change

In a particular lightning bolt, \(24 \;C\) of charge are transferred in \(0.21\; s\) through a potential difference of \(5.5 \times10^8\; V.\)

(a) What is the average current?
(b) How much electric potential energy is dissipated?

The relationship between charge \((q)\), time \((t)\) and current \((I)\) is:

(A)   \(I = qt\)

(B)   \(I = t/q\)

(C)   \(I = q/t\)
