A 6 V battery of negligible internal resistance is connected to a 1 Ω resistor in series with a parallel pair of 3 Ω and 6 Ω resistors. What current flows from the battery?
Answer and explanation
Correct answer: A. 2 A
- Step 1: Parallel pair: Ω.
- Step 2: Total resistance Ω, so A.
Answer
2 A.
Why not the others: 3/5 A: all resistors are treated as in series. 6 A: the parallel pair is ignored.
