(It's not exactly 12V because of resistance in the primary and imperfect coupling between the two windings. In other words, Fourier series can be used to express a function in terms of the frequencies (harmonics) it is composed of. This is a Class D or switching amplifier circuit. #2. This circuit is a flip-flop or latch, which stores one bit of memory. When the simulator starts up, there is 5V across the inductor, and no current. The transistor does two things: 1) it isolates the zener current from the LED current; 2) it amplifies the zener current so the turn on happens more or less when the zener starts to conduct instead of being a soft turn on. The top one is being driven at a slightly lower frequency, and the bottom one. The peak voltage dropped across a. for a voltage-controlled source, or i for a current-controlled source). This keeps Q1 switched on, in saturation mode, allowing a. The next line keeps the outputs the same otherwise. After a few seconds, the voltage is high enough to fire the spark gap.
