Question

In an experiment, it was observed that when the length of a wire in an electrical circuit is doubled, everything else remaining same, the current becomes half. On the other hand, if the thickness (diameter) of the wire is doubled, the current becomes 4 times. Two wires W1 and W2 of the same metal have the same current passing through them. The thickness of wire W2 is twice that of W1, then the length of the wire W2 is

Choices

Choice (4) Response

a.

two times that of wire W1

b.

four times that of wire W1

c.

sixteen times that of wire W1

d.
