Question

How can three resistors of resistences 2ohm 3ohm 6ohm be connected to give a total resistance of



a.4ohm



b.1ohm?

Answer 1

a)In order to get a resistance of 4 ohm, 3 ohm and 6 ohm resistor is connected in parallel and the equivalent resistance of these two resistors is connected in series with 2 ohm resistor.

b)In order to get a resistance of 1 ohm, all the resistors are connected in parallel.
