Question

1. Calculate the charge in a circuit which carries a current of 30 amperes for 5 seconds

2. how long would it take a circuit to deliver 500 coulombs of a charge with a current of 10 amperes

3. how many amperes of current would it take a circuit to produce a charge of 120C when turned on for 80s​

Answer 1

Answer:

1. 150C.

2. 50sec

3.1.5a

Explanation:

1. I = Q/T

Q= 30x5

=150c

2.applying the formulae, I = Q/T

T= Q/I

=500/10

=50sec.

3. using the formulae i=q/t

i= 120/80

=1.5a.
