What is (a) the highest, (b) the lowest total resistance that can be secured by combinationsof four coils of resistance 4 Ω, 8 Ω, 12 Ω, 24 Ω?

Answer»

Answer:

The answer to this question is

(a) 48 ohm

(b) 2 ohm

Explanation:

The highest RESISTANCE is =

R = R1 + R2 + R3 + R4

R = 4 + 8 + 12 + 24

R = 48 ohm

The longest Resistance is =

1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4

1/R = 1/4 + 1/8 + 1/12 + 1/24

1/R = 1/2

R = 2 ohm.

Therefore The LOWEST resistance = 2 ohm.

I HOPE IT WILL HELP YOU.
