Question

A charge of 2C moves between two plates maintained at a potential difference of 1V. What ia the energy acquired by the charge ?

Answer 1

Explanation:

As per the given conditionsQ = 2 C, Potential difference V = 1V.

Putting the known values in equation (i),

Energy acquired by the charge,

W = QV

= 2 x 1

= 2 Joule

Energy acquired by the charge= 2 Joule

Answer 2

Answer: 2 Joule.

Explanation:

• Given, Charge(Q)=2 Coulombs and potential difference (V)=1 Volt.
• We know that to calculate the work done W by a charge Q separated by a potential difference V is given by

       W= Q*V

    ⇒W= 2*1

     ∴ W= 2 Joule

• Hence, the work done by a charge of 2 Coulombs separated by a potential difference of 1 Volt is 2 Joule.
