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.
(a) Name two factors on which the specific resistance of a wire depends? (b) Two wires A and B are made of copper. The wire A is long and thin, while the wire B is short and thick. Which will have more specific resistance?
Which has more resistance: (a) a long piece fo nichrome wire or a short one? (b) a thick piece of nichrome wire or a thin piece?
Which will offer more resistance a short wire or a long wire? Give reasons.
Resistance of a long wire will be ___ the resistance of short wire
