A 12 V battery is connected to a 6 Ω resistor and a 3 Ω resistor in parallel. What is the total current?
Answer and explanation
Correct answer: D. 6 A
- Step 1: For parallel resistors 1/R = 1/6 + 1/3 = 1/2, so R = 2 Ω. Step 2. I = V/R = 12/2 = 6 A. Answer: 6 A. Why not the others: A series connection would give 9 Ω and 1.33 A.
