Work done in moving a charge AQ up through the potential difference V is given be

Correct answer: C. W = VAQ

  • A. W = AQ/V
  • B. W = V/AQ
  • C. W = VAQ
  • D. W = I/VAQ

Explanation

The correct expression for the work done in moving a charge Q up through the potential difference V is:W = VAQThis equation represents the work done (W) as the product of the potential difference (V) and the charge (Q) being moved. The expression VAQ is the correct form based on the context of the question.

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
