Q. 94.3( 13 Votes )

Which of the following represents voltage?
A.

B. Work done × Charge

C. Work done × Time/Current

D. Work done × Charge × Time

Class 10th NCERT - Science Exemplar 12. Electricity

Answer :

Work done is given by the relation :

W= charge × potential difference

W= Q × V

As we know that Q= I × t

Therefore putting in above equation

W= I × t × V

V= Work done/ Current × time
