Two copper wires have equal length but the thickness of one is twice that of the other. If the resistance of the thin wire is `10 Omega`, find the resistance of the thick wire.

Text Solution

Verified by Experts

(i) Resistance ` R prop (1)/(A)`. Determine the resistance of the wire using the formula, `(R_(1))/(R_(2))=(A_(2))/(A_(1))`
(ii) ` 2.5 Omega`
