Question

the least resistance obtained by using two 2 ohm 4 ohm 1 ohm and 100 ohm is​

Answer 1

Explanation:

Given data:

R_1 = 2 ohm

R_2 = 4 ohm

R_3 = 1 ohm

R_4 = 100 ohm

Lowest resistance is obtained when resistance is placed in parallel.

Given parallel combination is shown in figure:

\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} + \frac{1}{R_4}

\frac{1}{R_{eq}} = \frac{1}{2} + \frac{1}{4} + \frac{1}{1} + \frac{1}{100}

\frac{1}{R_{eq}} =1.76 ohm
