Spintronic Transistor Value PackOverview This spintronic transistor is a voltage controlled resistor. The higher the voltage on the top sprocket, the lower the resistance of the bottom sprocket. Transistors greatly expand the range of circuits that can be built. They are a critical part of many analog circuits and are ubiquitous in digital circuits. Detailed description The transistor can be manually adjusted to control whether the transistor turns on by turning the top sprocket
