Question

If 24 C charges flow in 4 sec. What is the value of current ?
5 A
6 A
28 A
20 A​

Answer 1

Given:-

• Charge ,Q = 24C

• Time taken ,t = 4 S

To Find:-

• Value of current ,I

Solution:-

As we know that Current is defined as the charge per unit time .

→ I = Q/t

Substitute the value we get

→ I = 24/4

→ I = 6 A

∴ The value of current is 6 Ampere

Additional Information !!

•Potential Difference: The potential difference between two point in an electric circuit carrying some current as the work done to move a unit charge from one point to the other.

•Potential difference = Work done /Charge.

•V = W/Q

here

V is the potential difference

W is the work done

Q is the charge

• SI unit of electric potential energy is volt (V).

• 1 volt : The potential difference between two points in a current carrying conductor when one joule of work is done to move a charge of one coulomb from one point to other.

• 1 Volt = 1Joule/1Coulomb
