Question

A lightning bolt carrying 30,000 A lasts for 50 micro-seconds. If the lightning strikes an airplane flying at 20,000 feet, what is the charge deposited on the plane?

Answer 1

1.5 Columb charge is deposited on the plane.

Step-by-step explanation:

The relationship between charge and current is:

Current = Charge/Time

Therefore,

Charge = Current x Time

We have,

Current = 30,000 A

Time = 50 micro-seconds = 50 x 10^(-6) sec

Using these values:

Charge = [30,000 A][50 x 10^(-6)]

Charge = 1.5 C
