Question

Given n resistor each of resistance R . How will you combine them to get the: 1. maximum2. MinimumWhat is the ratio of maximum to minimum resistance

Answer 1

Answer:

$n {}^{2}$

is the answer

Answer 2

Answer:

1. To get maximum resistance, connect all the n resistors in series.

2. To get minimum resistance, connect all the n resistors in parallel.

Ratio of maximum to minimum resistance is -- nR / R/n

                                                                       = n²R / R

∴Ratio of maximum to minimum resistance is = n²
