Question

If the least resistance that can be obtained by combining resistance of 6 ohm, 3 ohm and x ohm is 1 ohm,

then find the value of x.​

Answer 1

Answer:

Maximum and minimum resistance is 9 and 1 ohm respectively.

Explanation:

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