Question

The amount of charge passing through a cell in 4 seconds is 12C. Find the current supply by the cell.

Answer 1

Answer:

time= 4 sec

charge taken = 12 coulomb

I = Q/T

I=12/4

I=3 A

Hope it helps you

Answer 2

Given: The amount of charge passing through a cell in 4 seconds is 12 C.

To find: The current supply by the cell.

Solution:

The electric current in a conductor is defined as, "The rate of flow of electric charge through a conductor." It is given by the following formula.

$I = \frac{q}{t}$

Here, I is the electric current, q is the charge in the conductor and t is the time period. In the given question, the cell is the conductor, 12 C is the charge in it and 4 seconds is the time period. The S.I. unit of electric current is ampere (A).

$I = \frac{12 C}{4 s}$

   $= 3 A$

Therefore, the current supply by the cell is 3A.
