Question

Three 2.20 k resistors can be connected together in four different ways, making combinations of series and/or parallel circuits.

What is the net resistance of resistors connected in series and parallel?

Express your answer with the appropriate units.

What is the net resistance of two resistors in series connected in parallel with the third?

Express your answer with the appropriate units

What is the net resistance of two resistors in parallel connected in series with the third?

Express your answer with the appropriate units.

Explanation / Answer

net resistance of resistors connected in series = 3 * 2.20 = 6.6 kohm

net resistance of resistors connected in parallel = 2.20/3 = 0.733 kohm

net resistance of two resistors in series connected in parallel with the third = (4.4 * 2.2)/(4.4 + 2.2)

                                                                                                                  =   1.466 kohm

net resistance of two resistors in parallel connected in series with the third =   1.1 + 2.2

                                                                                                                   = 3.3 kohm
