Chapter 34, Problem 59A

How much current, in amperes, is in a lightning stroke that lasts 0.05 second and transfers 100 coulombs?

To determine

To find: The value of in lightning stroke

Explanation of Solution

The transfer of charge is $q=100\text{C}$ , and time period is $t=0.05\text{s}$ .

Current flow is

  $\begin{array}{c}I=\frac{q}{t}\\ =\frac{100\text{C}}{0.05\text{s}}\\ =2000\text{A}\end{array}$

Current flow is 2000 Ampere.
