Question

Fill in the blank

1 V = 1 __ $C^{-1}$

(in SI units)

• A. A
• B. V
• C. J
• D. I

Answer 1

The correct option is C

J

We know, V = W/Q, where V= Potential difference, W = work done, Q =Charge

Unit of work done, W= J (joule) and of charge, Q = C (coulomb)

Hence, 1 V = 1 J/1 C

$1V=1J{C}^{-1}$
