Question

What is (i) the highest, (ii) the lowest total resistance that can be secured by  combinations of four coils of resistance 5Ω, 10 Ω, 15 Ω, 30 Ω?​

Answer 1

Answer:

in series 60

in parrelel 2.5

Answer 2

Answer:

Ans: Given resistances R1 =4 Ω, R2=8 Ω, R3=12Ω, and R4=24Ω. ∴ 2 Ω is the lowest total resistance.
