Answer 1

Question:

A large lightning bolt had a 20,000 A current and moved 30.0 C of charge. What was its duration?

Solution:

I = Q/t

20,000 = 30.0/t

t = 30.0/20,000

t = 0.0015 seconds

t = 1.5 * 10⁻³ seconds

Explanation:

The current exist in the wires of a circuit when there is charge flowing through it.

The rate at which charge flows after a point in the circuit is said to be ekectric current.

It can be expressed as :-

I = Q/t

I => Current

Q => Quantity of charge

t => time

Current of 1 ampere ≡ 1 Coulomb of charge flowing past a point in 1 second

Quantity of charge on 1 electron = 1.6 * 10⁻¹⁹ C
