Question

1. Given five equal resistances; each of the value 5 ohms. (a) What is the maximum

resistance that can be obtained from them? (b) What is the minimum resistance that can be

obtained from them?
​

Answer 1

Answer:

And the highest possible would be connecting all of them in series. R1, R2, R3, R4, R5 in series equals to the sum of their individual resistance. So R1+R2+R3+R4+R5, since the resistors are all 5 ohms each, it's going to be 5 * 5 ohms = 25 ohms.

Answer 2

Explanation:

The minimum resistance possible by 5 equal resistance(each of value R) is 5R. This will happen when they will be in parallel.

So, 5R=2

or, R=10 ohm

The maximum resistance can be found when they will be in series i.e. 5R=50 ohm.
