Concept explainers
In terms of heating, why are thick wires rather than thin wires used to carry large currents?
To Explain: Thick wires are used to carry large currents.
Explanation of Solution
Introduction:
Resistance is a property of element which is introduced in a circuit or material of the conducting wire. Resistance of a wire depends on its length
A long and thin wire would have greater resistance as compared to a short and a fat wire.
When current is passed through a conducting wire, it heats up. If a thick wire is used, its resistance would be less and a large amount of current can flow easily otherwise a thin wire would not be able to carry large current as it would get heated up alot.
