Question

Determine the highest resistance that can be secured by combining 4 coils of resistance 3 ohm,6 ohm,9 ohm ,18 ohm

Answer 1

R1 = 3ohm

R2 = 6ohm

R3 = 9ohm

R4 = 18ohm

We know, that we will get the highest resistance when the resistances are connected in series Combination.

So, Equivalent Resistance

=>R1+R2+R3+R4

=> 3+6+9+18

=>36 ohm
