A long wire will have__________ for the same cross-sectional area.
More resistance than short wire
Less resistance than short wire
Same resistance as short wire
More tensile strength
Resistance of a wire is directly proportional to the length of the wire. So, a longer wire will have more resistance.
Four wires of same materials have the following dimensions: Wire 1: Length l, Cross section area A Wire 2: Length l, Cross section area 2A Wire 3: Length 0.5l, Cross section area 1.5A Wire 4: Length 2l, Cross section area 0.5A Which wire has the highest resistance?
