Calculate Work done in carrying 8C charge from 150 Volts to 200 Volts

 Calculate the amount of work done in carrying 8 Coulomb charges from a terminal of 150 volts to 200 volts.

Given values

Charge (Q) = 8 C

Potential (V₁) = 150 volt

Potential (V₂) = 200 volt

Potential difference (V) = V₂ -V₁

    V=   200 – 150 = 50 volt

Work (W) =?

Solution 

  `V=W/Q`

  `W=VQ`

  `W=50× 8=400 J`
