A current of 4mA is flowing through a conductor in 20s calculate the charge flowing through itI need it quickly plsstep by step answer ​

Answer»

Given:-

→ Current flowing = 4 mA

→ Time = 20 s

To FIND:-

→ Charge flowing through the conductor.

Solution:-

Firstly let's convert the unit of current from mA to A.

⇒ 1 mA = 0.001 A

⇒ 4 mA = 4(0.001)

⇒ 0.004 A

________________________________

Now, we know that :-

i = Q/t

Where :-

• i is the current flowing.

• Q is the charge.

• t is time.

Substituting VALUES, we get :-

⇒ 0.004 = Q/20

⇒ Q = 20(0.004)

⇒ Q = 0.08 C

Thus, the charge flowing is 0.08 C .
