Question

As the cloud passes over the building, a lightning strike occurs and a charge of 0.84C flows through the lightning conductor. The charge flows for 3.5 × 10^-5 s.
Calculate the average current in the lightning conductor during this time. State the formula used in your answer

Answer 1

Answer:

I=24,000 Amp

Explanation:

Electric Current

Is a measure of the quantity of charge Q flowing by a point in a time period of t.

The standard metric unit for the current is the Ampere, often abbreviated as Amps or A.

It can be calculated as:

$\displaystyle I=\frac{Q}{t}$

The cloud generates a lightning strike that releases a charge Q=0.84 C during a time $t=3.5\cdot 10^{-5}\ sec$.

The current is of course, not of a constant value, but an average value can be calculated by using the above formula:

$\displaystyle I=\frac{0.84}{3.5\cdot 10^{-5}}$

$\boxed{I=24,000\ Amp}$
