C) \[\operatorname{R}\text{ }=\text{ 1}5\text{ }\Omega ,\operatorname{L}\text{ }=\text{ 3}.5\text{ }\operatorname{H}, C\text{ }=\text{ 30 }\mu \operatorname{F}\]
D) \[\operatorname{R}\text{ }=\text{ 2}5\text{ }\Omega ,\operatorname{L}\text{ }=\text{ 1}.5\text{ }\operatorname{H}, C\text{ }=\text{ 45 }\mu \operatorname{F}\]
Correct Answer: C
Solution :
| Option [c] is correct. |
| Explanation: Quality factor (Q) of an L-C-R Circuit is given by, \[\operatorname{Q}=\frac{1}{R}\sqrt{\frac{L}{C}}\] |
| Tuning of an L-C-R circuit depends on quality factor of the circuit. Tuning will be better when quality factor of the circuit is high. |
| For Q to be high, R should be low L should be high and C should be low. Therefore, option is most suitable. |
