Question

A current of 150mA flows through a circuit for 2 min. Find the amount of charge that flows through the circuit

Answer 1

Answer:

I=150 ma = 150 x 10 to the power -3 A  

t= 120s  

q=i/t

q= 150/ 1000x 120

q= 0.00125 C

Answer 2

Current flows through circuit = 0.150 A

Time given = 2 min or 120 sec

We know that charge flows through the circuit is the product of current and time. Hence,

Q = It

Q = 0.15×120

Q = 18 C
