8.78 An automobile airbag igniter is modeled by the circuit in Fig. 8.122. Determine the time it takes the voltage across the igniter to reach its first peak after switching from A to B. Let R = 3 ฮฉ, C = 1โ30 F, and L = 60 mH.
8.79 A load is modeled as a 100-mH inductor in parallel with a 12-ฮฉ resistor. A capacitor is needed to be connected to the load so that the network is critically damped at 60 Hz. Calculate the size of the capacitor.
8.83 Figure 8.124 shows a typical tunnel-diode oscillator circuit. The diode is modeled as a nonlinear resistor with iD = f (vD), i.e., the diode current is a nonlinear function of the voltage across the diode. Derive the differential equation for the circuit in
terms of v and iD.
