Problem 11-46 Current and potential change - Part 2 - C

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?


Accumulated Solution

\(I = q/t = 24 C/0.21 \;s = 1.1 \times 10^2 A \quad \text{ (answer to part (a))}\)


No. You can see its not correct from the units

\([\Delta V] = \text{volts} = J/C\)

\(\Delta V = q \Delta U\) means \(J/C = CJ\) which is not true.

Try again.
