Which has less electrical resistance : a thin wire or a thick wire (of the same length and same material)?

उत्तर

A thick wire has a greater area of cross-section, whereas a thin wire has a smaller area of cross-section. Also, the resistance of a conductor is inversely proportional to its area of cross-section. This means that a thick wire has lesser resistance than a thin wire.
