Question

What is
a). the highest
b) the lowest, total resistance that can be secured by combination of four coils of resistance 4ohm 8ohm 12ohm 24ohm

Answer 1

Heya !!


here is your answer !!


total higest resistance =>

it will come in series


then , equivalent resistance =>


4 Ω + 8Ω + 12 Ω +24 Ω => 48 Ω


now ,



lower resistance is => connecting them in parallel


=> 1 / 4 Ω + 1 / 8 Ω + 1 / 12 Ω + 1 / 24 Ω


=> 1 / Rp = 2 Ω


hence ,


the height resistance is 48 Ω


and Lowest resistance = 2 Ω .


hope it helps you dear a lot !!!!


thanks !!
