Question

What is the minimum resistance which can be made using five resistors each of 1/2 ohm​

Answer 1

Answer:

Minimum possible possible resistance by using five 1/5 ohm=1/25=0.04 Ohm i.e 40mili Ohm.

Answer 2

Answer:  minimum resistance can made by connecting resistors in parallel.

• Total resistance is calculated by  $\frac{1}{R} = \frac{1}{R1} + \frac{1}{R2} + \frac{1}{R3}$

                                       $\frac{1}{R} = \frac{1}{R1} + \frac{1}{R2} + \frac{1}{R3} + \frac{1}{R4} + \frac{1}{R5}$

                                ==>          R = 1/10
