일반물리학 2 — Electromagnetic Oscillations and Alternating Current: Problem 3

3 In Fig. 31-19, a generator with an adjustable frequency of oscillation is connected to resistance $R = 100 \Omega$, inductances $L_1 = 9.70 \text{ mH}$ and $L_2 = 2.30 \text{ mH}$, and capacitances $C_1 = 8.40 \mu\text{F}$, $C_2 = 2.50 \mu\text{F}$, and $C_3 = 3.50 \mu\text{F}$. (a) What is the resonant frequency of the circuit? (Hint: See Problem 11 in Chapter 30.) What happens to the resonant frequency if (b) $R$ is increased, (c) $L_1$ is increased, (d) $C_3$ is removed from the circuit, and (e) $L_2$ is removed?
