Question 10 - MCQs from (Past Year Papers & NCERT Exemplar) - Chapter 12 Class 10 - Electricity

Last updated at Dec. 13, 2024 by

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).
