Which of the following represents voltage? 

(a) \frac{Work \; done}{Current \times Time}

(b) Work \; done \times Charge

(c) \frac{Work \; done \times Time}{Current }

(d) Work \; done \times charge\times Time

Answers (1)

Answer:  (a)

Solution:

Work done = Voltage × charge

Now, Charge = Current × Time               (q = It)

Work done = Voltage × Current × Time

Voltage =

               \frac{Work \; done}{Current \times Time}

Therefore, option (a) is correct.
