What is the minimum resistance that can be made using five resistors, each of [tex]\frac{1}{5}[/tex] ohms?

Asked by BariKrupka

Answer (2)

The minimum resistance to the flow of electrical current is achieved when the resistors are connected in parallel, just as the minimum resistance to the flow of vehicular traffic is achieved when several lanes are built in parallel.
When 5 equal resistors are connected in parallel, the net resistance of their combination is just 1/5 of the value of each one.
So 5 equal resistors in parallel, each with a resistance of 1/5 ohm, have a combined net resistance 0f 1/25 ohm .

The minimum resistance that can be achieved using five resistors of 5 1 ​ ohm each, when connected in parallel, is 25 1 ​ ohms. This is calculated using the formula for equivalent resistance in parallel circuits. Therefore, connecting resistors in parallel lowers the total resistance significantly.
