Question

What is the maximum and minimum effective resistance can create by using ten 2 Ω resistors

Answer 1

Answer:

maximum resistance is created when the resistors are in series

and minimum is created when resistors are parallel

$maximum \: resistance = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 \\ = 20ohm \\ minimum \: resistance = \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} \\ = \frac{10}{2} \\ = 5ohm$
