Teaching HTET TGT Level 2 - 2024 Mock Test Physics Current, Resistance and Electricity Combination of Resistors — Series and Parallel
Two copper conductors have equal length. The cross-sectional area of one conductor is four times that of other. If the conductor having smaller cross-sectional area has a resistance of 40 Ω the resistance of the parallel combination will be is:
1
10 Ω
2
40 Ω
3
8 Ω
4
5 Ω
