Question

Is this correct:
A current of 2 amps flows in a circuit how long does it take for 8 coulombs to flow past a certain point. is the answer 4seconds if so please can you tell me the working out.

Answer 1

Yes, the answer is 4 seconds!

We know that the current flowing I = 2 A

Charge flowing past a certain point Q = 8 C

Time taken t = ?

We use the equation Q = It

Plugging in the numbers, we have 8 = (2)(t)

Solving for t, we easy that t = 4 s.

Answer 2

Yes. 4 seconds.

Current = charge / time

Time = charge / current

Charge = current • time
