Question 92

Two 12 Ω resistors are connected in series and then in parallel.

What is the combined resistance in each case?

A

Series = 12 Ω12\ \Omega12 Ω, Parallel = 6 Ω6\ \Omega6 Ω

B

Series = 12 Ω12\ \Omega12 Ω, Parallel = 12 Ω12\ \Omega12 Ω

C

Series = 24 Ω24\ \Omega24 Ω, Parallel = 6 Ω6\ \Omega6 Ω

D

Series = 24 Ω24\ \Omega24 Ω, Parallel = 12 Ω12\ \Omega12 Ω
