HW-17 due March 18 17-1. (HRW 31-1) In a certain oscillating LC circuit, the total energy is converted from electrical energy in the capacitor to magnetic energy in the inductor in 1.50 μ s. What are (a) the period of oscillation and (b) the frequency of oscillation? (c) How long after the magnetic energy is a maximum will it be a maximum again? 17-2. (HRW 31-11) In Fig. 31-28 , , , and , and the ideal battery has emf . The switch is kept in position a for a long time and then thrown to position b . What are the (a) frequency and (b) current amplitude of the resulting oscillations? Figure 31-28 17-3. (HRW 31-13) An oscillating LC circuit consisting of a 1.0 nF capacitor and a 3.0 mH coil has a maximum voltage of 3.0 V. What are (a) the maximum charge on the capacitor, (b) the maximum current through the circuit, and (c) the maximum energy stored in the magnetic field of the coil? through the circuit, and (c) the maximum energy stored in the magnetic field of the coil?...
