The lightning discharge time is 3 ms. The current in the lightning channel is about 30 kA. What charge passes through the lightning channel?
t = 3 ms = 3 * 10 ^ -3 s.
I = 30 kA = 30 * 10 ^ 3 A.
q -?
According to the definition, the current strength I is a quantity that shows what charge q passes through the conductor per unit time t.
I = q / t.
q = I * t.
q = 30 * 10 ^ 3 A * 3 * 10 ^ -3 c = 90 Cl.
Answer: a charge of q = 90 C passes through the lightning channel.
