Question

Calculate the highest resistance that can be secured by combinations of four coils of resistances 4 Ω, 8 Ω, 12 Ω, 24 Ω?​

Answer 1

48 Ω

Given:

Resistances of four coils = 4 Ω, 8 Ω, 12 Ω and 24 Ω

To Find:

The Highest Resistance That Can Be Secured By The Combination.

Calculating:

Formula that we use to calculate the highest resistance connected in the form of series:

Rn = R1 + R2 + R3 + R4

Substituting all the values that are known to us in this formula we get:

Rn = 4 + 8 + 12 + 24

Rn = 48 Ω

Ω - This symbol represents Ohm. It is the SI unit of electrical resistance. It was named after the German physicist Georg Simon Ohm.

Therefore, the highest resistance that can be secured by combinations of the four coils which is connected in series is 48 Ω.
