Question

Calculate the work done in moving a change
of 3c through a
potential difference of
20v ​

Answer 1

Given:-

• Charge ,Q = 3 C

• Potential Difference ,V = 20v

To Find:-

• Work done,W

Solution:-

As we know that

• V = W/Q

Substitute the value we get

→ 20 = W/3

→ W = 20×3

→ W = 60 J

Therefore, the work done by the body is 60 Joules.

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
