A certain circuit is composed of two parallel resistors. The total resistance is 1,403 Ω. One of the resistors is 2 kΩ. The other resistor value is____________?
Correct answer: B. 4.7 kΩ
- A. 1,403 Ω
- B. 4.7 kΩ
- C. 2 kΩ
- D. 3,403 ΩHire Civil Engineers
Explanation
For parallel resistors, 1/Rt = 1/R1 + 1/R2. Substituting 1,403 Ω and 2,000 Ω gives the other resistance approximately 4,700 Ω, or 4.7 kΩ.
