Which of the following represents voltage?
(a) Work done/Current ×Time
(b) Work done × Charge
(c) Work done×Time/Current
(d) Work done × Charge/Time
Answer:
Voltage is the potential difference between 2 points.
We know that,
- Potential difference = Work done / Charge —---------(i)
- Charge = Current * Time —---------(ii)
Substituting (ii) in (i),
Potential difference = Work done / Current * Time
So, the correct answer is (a).
