Question

Arrange the following resistors of 6 ohm, 3 ohm and 2 ohm in such a way that you get the total resistance of 4 ohm and 4.5 ohm.

Answer 1

2: Place that parallel combination in series with the other 2 ohms to get 4 ohms, since series resistances simply add [2+2=4]. The resulting series/parallel hybrid combination achieves the required equivalent resistance, which can be expressed more simply in the following form (3 ohms)//(6 ohms) + 2 ohms = 4 ohms
