Question

A 6 V battery is connected to the terminals of the three-metre long wire of uniform thickness and resistance of 100 Ω . The difference of potential between two points on the wire separated by a distance of 50 cm will be, 1 . 5 V, 3 . 0 V, 1 . 0 V, 2 . 0 V

MARKS App · Accepted Answer

R ∝ ℓ For 300 cm , R = 100 Ω For 50 cm , R ' = 100 300 × 50 = 50 3 Ω ∴ IR = 6 ⇒ IR ' = 6 R × R ' = 6 100 × 50 3 = 1 V
