Two 10 ohm resistors in parallel are connected in series with a 5 ohm resistor. What is the total resistance?
Answer and explanation
Correct answer: A. 10 ohms
- Step 1: The parallel pair gives 5 ohms. Step 2. In series with 5 ohms the total is 10 ohms. Answer: 10 ohms. Why not the others: 25 ohms adds everything in series.
