NOTES: The 1000 giga-ohm resistor is acting as a voltmeter, measuring across both the inductor & 300 ohm resistor together. Thus, I added the necessary info to a new Field in the Kicad symbol’s property panel. Lab 3 - Circuits . com/circuit/ simulator. With the transistor removed, the inductor and two capacitors form a resonant circuit, like the LRC example. Over time, the voltage across the inductor decreases, allowing the flow of current to slowly increase until it acts as a closed. It is currently just lightning the LED, not doing the other functions. As its voltage approaches the source voltage (the 5V voltage source shown on the left), the current flowing into the capacitor decreases. Current Circuit: Square Wave Generator. It uses two tri-state buffers; the implementation of each buffer is shown in full. Current moves back and forth as the capacitors charge and discharge through the inductor.
