Resistors of 3 Ω, 3 Ω and 6 Ω are connected in series. What is the total resistance?

Answer and explanation

Correct answer: A. 12 Ω

  1. Step 1: In series the resistances add: .
  2. Step 2: Ω.
Answer
12 Ω.
Why not the others: 6/5 Ω: that is the formula for resistors in parallel. 54 Ω: it multiplies the resistances. 6 Ω: it takes the largest value only.
