Question

what is the highest and lowest resistance that can be obtained from four coils of resistance 4 ohm ,8 ohm, 12 ohm, 24 ohm​

Answer 1

Explanation:

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

Answer 2

Answer:

Highest resistance : 48 ohm

Here lowest resistance will be the average of all resistance :48/4=12ohm
