Question

4 J of energy is gained by one Coulomb of charge passing through a battery whose one terminal has
+7 V potential and the other terminal has 'X' V potential. What is the value of X?
(A) -28
(B)-3
(C) +3
(D)-11
(E) +28​

Answer 1

Answer:

Explanation:

Energy    E=qΔV

Charge   q=1 C

Potential difference   ΔV=6 volts

So,   E=1×6=6 J
