State the factor on which resistance depends |
|
Answer» Length, Cross-Sectional Area, Temperature, Type of MaterialExplanation:1) Length => Longer MATERIALS have greater resistance, as electrons have to travel a longer PATH. Think of a road- longer road TAKES more time to travel across, so more resistance2) Cross Sectional Area => Larger area have lower resistance. Just think of a road - more wider the road, LESS TRAFFIC, so cars (electrons) can travel faster, so less resistance.3) Temperature => Higher temperature material has less resistance, as electrons have more kinetic energy.4) Type of material => This factor is more subjectiveHope this helps!! |
