Question

A current of 15mA flows through a circuit for 2min. Find the amount of charge that flows through the circuit​

Answer 1

Answer:

The formula is

Current = Charge / Time

Putting values...

Current= 15 mA

Time = 2 min

Charge = ? (To find)

-> 15 = Charge / 2

-> Charge = 15× 2

= 30 coulomb

Hope it helps...

Answer 2

Answer:

As we know that

I=Q/T

therefore Q=I/T .

15 mA =

$\frac{15}{1000} amperes$

and

2 min =120 sec

therefore according to the above equation

Q =

$\frac{15}{1000}$

divide by 120

we get 15×120/1000

= 1.8 C of charge .
