1.

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

Answer»

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 !!
