Question 33
Current ElectricityIn the diagram above, the values of V1 and V2 are respectively
- A.1 V and ⅓ V
- B.⅓ V and 1 V
- C.⅓ V and ⅔ V
- D.1 V and ⅔ V
Show the answer and explanation
Answer: D (1 V and ⅔ V)
Explanation
Total resistance = 3 + 2 + 1 = 6 Ω, so I = 2/6 = ⅓ A. V1 = ⅓ × 3 = 1 V and V2 = ⅓ × 2 = ⅔ V.
