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.

All these sentences are true.

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.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
