The ratio of resistance of two copper wires of the same length and of same cross-sectional area when connected in series to that when connected in parallel is

View answer and explanation

Correct option: D

4: 1

Option D (

4: 1

) is correct because the ratio of resistances in series to parallel for two equal resistors is 4:1.
