Which of the following combination should be selected for better tuning of an LCR circuit used for communication?
For tuning a LCR circuit, its selectivity should be high. High selectivity is observed in circuits with high quality factor.
For option (a), Q=7.3
For option (b), Q=8.28
For option (c), Q=9.43
For option (d), Q=22.77
Hence, option (d) gives the best combination.
