11. 1 volt= 1 joule/ 1 coulomb
6v= x joule / 1 coulomb
6×1=6 joules

11. Potential Difference = Work done / Charge
V = W / Q
GIVEN
Potential Difference = 6V
Work Done = Energy = W
Charge Q = 1C
∴ Potential Difference = Work done / Charge
V = W / Q
6V = W / 1
6*1 = W
Work = Energy = 6 J
12. The resistance of a conductor depends on the area of cross-section of the conductor. Actually, the resistance of a conductor is inversely proportional to the area of cross-section of the conductor. Material: The resistance of a conductor depends on the nature of material of the conductor.
