Q9 of 22 Page 344

How can three resistance of 2, 3 and 6 ohms be connected so as to give a total resistance of 1 ohm?

If we connect the given three resistors as shown in the figure below then we get net resistance as 1Ω. Here all the resistors are connected in parallel.


∴their equivalent resistance will be given as



⇒


⇒ Req = 1 Ω.


Therefore, the resistances must be connected in parallel to get equivalent resistance of 1 Ω.
