A 24 V battery of negligible internal resistance is connected to a 4 Ω resistor in series with a parallel pair of 6 Ω and 3 Ω resistors. What current flows from the battery?
Answer and explanation
Correct answer: D. 4 A
- Step 1: Parallel pair: Ω.
- Step 2: Total resistance Ω, so A.
Answer
4 A.
Why not the others: 24/13 A: all resistors are treated as in series. 6 A: the parallel pair is ignored.
