A thin wire has MORE resistance than a thick wire.

A short wire has LESS resistance than a long wire.

A warm wire has MORE resistance than a cool wire.

A thin wire has resistance than a thick wire. more

A short wire has resistance than a long wire. less

A warm wire has resistance than a cool wire. more

All these sentences are true.

Explanation:

The resistance of a wire varies directly with the length of the conducting wire and varies inversely with the cross sectional area of the conductor.

The formula is given by R = ρ L/A.

So the longer the wire, the more the resistance. The thinner the wire, the more the resistance.

Now, the resistance of a conductor depends with temperature as

R = R (ref) [1 + α{T - T (ref) }]

As the conductors have a positive value for α, so the resistance of conductors will increase with increase in temperature.
