We know that in a parallel combination of resistors the net resistance, $\frac{1}{R_{P}} = \frac{1}{R_{1}} + \frac{1}{R_{2}} + \frac{1}{R_{3}} + . . . .$ and when they are connected in series then net resistance is, $R = R_{1} + R_{2} + R_{3} + . . . . . . + R_{n}$ . A square-shaped wire with a resistance of each side is, $3 Ω$ , then the circuit is,
then the net resistance is $3 Ω$ .
