The current in the lightning channel is 20,000 A. What electric charge does the lightning transfer from the cloud to the Earth in 50 μs?
The electric charge that the lightning carries is calculated by the formula:
q = I * t, q is the charge carried by the lightning (C), I is the current in the lightning channel (I = 20,000 A), t is the time the charge passes (t = 50 μs = 50 * 10 ^ -6 s).
Let’s calculate the value of the electric charge:
q = I * t = 20,000 * 50 * 10 ^ -6 = 1 Cl.
Answer: Lightning will transfer a charge equal to 1 C from the cloud to the ground.
