Question

the minimum possible resistance that can be obtained by using three resistor 2ohm, 4ohm and 4ohm​

Answer 1

Answer:

1 ohm

Explanation:

minimum resistance will be obtained when they are connected in parallel

so resolve the equvalent resistance of 2,4,4 ohm resisters in parallel

4&4 in parallel so resultant=4/2=2

then this 2 and the first 2 ohm resistor in parallel

so resultant=2/2=1

answer=1 ohm
