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?

Open in App

Solution

(a) Resistance is directly proportional to the length of the wire, hence the long piece of Nichrome has more resistance

(b) Resistance is inversely proportional to the Area of cross-section of the wire, hence the thin piece of Nichrome has more resistance
