Question

What is the voltage of a source which provides 12.0 j to each coulomb of charge present?

Answer 1

W=12J As there is each columb so Q=1C So V=12V to each columb of charge present.

Answer 2

Answer: The correct answer is 12 V.

Explanation:

The expression of the work done in terms of charge and voltage is as follows;

W=qV

Here, q is the charge, W is the work done and V is the voltage.

It is given in the problem that the voltage of a source which provides 12.0 j to each coulomb of charge.

Calculate the voltage.

Put W= 12 J and q= 1 C in the above expression.

12=(1)V

V= 12 V.

Therefore, the voltage of a source is 12 V.
