Question 27
Current ElectricityWhat is the resultant resistance of the circuit (Fig. 6) given above?
- A.11 Ω
- B.8 Ω
- C.4 Ω
- D.3.6 Ω
- E.4.3 Ω
Show the answer and explanation
Answer: B (8 Ω)
Explanation
The two 2 Ω resistors in parallel give 1 Ω; in series with 3 Ω and 4 Ω the total is 3 + 1 + 4 = 8 Ω.
