Question

show how you connect 3 resistors,each of resistance 6 ohm,so that the combination has a resistance of (¡)9 ohm (¡¡) 4 ohm
​

Answer 1

Answer:

To obtain a combined resistance of 9 ohms, three resistors each of resistance 6 ohm should be connected in a parallel circuit and one in series. In a parallel circuit, the equivalent resistance of all the resistors connected is equal to the reciprocal value of the sum of the individual resistances.
