To prevent the cable overheating, how should the cable be changed, and why?
A Use thicker copper cable which has less resistance.
B Use thicker insulation which stops the heat escaping.
C Use thinner copper cable which has more resistance.
D Use thinner insulation which allows less heat to escape.

The answer is A.

its A cos thiCKEr copper cable has less resistance as it is inversely proportional 2 area. N resistance heats da cables so this is how u prevent it frm overheating!!
