A typical lightning bolt may last for 0.200 s and transfer 1.00 × 1020 electrons. Calculate the average current in the lightning bolt.

To determine
The average current in the lightning bolt

Explanation

Given Info: The lightning bolt existed for 0.200s transferred 1.00×1020 electrons

Explanation:

Formula to calculate the average current is,

Iav=ΔqΔt

• Iav is the average current in the lightning bolt,
• Δq/Δt is the rate of flow of charge,

The total charge due to electron flow is,

q=ne

• n is the number of electrons flown,
• e is the charge of the electron

Substitute equation for total charge in the above equation

Iav=net

Substitute 1.00×1020 for n , 1
