Question

I WILL FAN AND GIVE MEDAL! Which type of wire would have the least resistance?
thick, short, hot
thick, long, hot
thin, short, hot
thin, long, cold
thick, short, cold

Answer 1

Width has the most effect on resistance, followed by length then temperature.

It is thick, short then cold

Answer 2

resistance of a wire is given by,
R=resistivity x length/area of cross section of wire
here resistivity is a characteristic property of a material which increases with temperature.

Answer 3

Thanks guys!
