Four 12 Ω resistors are connected together. What is the maximum resistance that can be attained with these resistors by connecting them in various ways?
A) 12 Ω
B) 24 Ω
C) 36 Ω
D) 48 Ω
E) 44 Ω

Question

Quizplus · Accepted Answer

The maximum resistance can be attained by connecting all four 12 Ω resistors in series. When resistors are connected in series, their resistances add up. Therefore, the maximum resistance is 12 Ω + 12 Ω + 12 Ω + 12 Ω = 48 Ω.
