Question

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

Answer 1

Answer:

Explanation:

if all of these coils are connected in series it will give maximum resistance

4+8+12+24= 48 ohm

if all of these are connected in parallel then it'll give lowest resistance possible,

1/4+1/8+1/12+1/24= 6/24+3/24+2/24+1/24= 12/24

= 1/2 ohm
