A coil with zero resistance has its ends labeled a and b. The potential at a is higher than at b. Which of the following could be consistent with this situation?

Mark all that apply

a. The current is constant and is directed from a to b.

b. The current is constant and is directed from b to a.

c. The current is decreasing and is directed from b to a.

d. The current is increasing and is directed from a to b.

e. The current is increasing and is directed from b to a.

f. The current is decreasing and is directed from a to b.

A - The current is constant and is directed from a to b

Explanation:

when the resistance value becomes high, then, the current flow will decrease and on the other side the resistance value is low, the current flow is going to be increase when the potential difference remains constant in the circuit.

Also, the resistance is going to be zero, thus, the current flow is going to remain constant if the potential difference remains has constant.

Therefore, the statement which consistent with the situation is the current is constant and is directed from a to b.

b. The current is constant and is directed from b to a

Explanation:

Since there is zero resistance, current will flow through the coil endlessly without diminishing. This is because energy is not lost as heat as it would have been if there was a resistance to the flow of current.

Also, current flows in the opposite direction of the potential difference. Since a is higher than b then, potential difference will be from a to b and current will be from b to a.
