Question

If the least resistance that can be obtained by combining resistance of 6 ohm,3 ohms, and x ohm ,then find x ?

Answer 1

Answer:

Maximum and minimum resistance is 9 and 1 ohm respectively.

All resistor are of same resistance , R = 3 ohm. We know, equivalent resistance is maximum when all resistance are in series. Also, equivalent resistance is minimum when all resistance are in parallel

Answer 2

Answer:

the max and minimum distance is 1 ohm and 9
