Physics · Alternating Current
For better tuning of a series LCR circuit in a communication system, the preferred combination of components is:
- 1R = 15 Ω, L = 20 H, C = 45 μF
- 2R = 25 Ω, C = 45 μF, L = 15 H
- 3R = 15 Ω, L = 40 H, C = 20 μF✓
- 4R = 20 Ω, C = 35 μF, L = 15 H
Correct answer
R = 15 Ω, L = 40 H, C = 20 μF
