Fast practice, instant feedback. Timer auto-submits when time’s up.
Avg score: 0% Most missed: “How many layers and junctions does an SCR have?”
Solid State Electronic Devices topics include: Solid state electronics, pn junction diode, BJT, FET, thyristors, diac, triac, light emitting diode and optical isolation. Solid-state electronic devices are electronic devices that use semiconductor materials like silicon, germanium, or gallium arsenide. They work by using electrical phenomena at the junctions between semiconductors, metals, and insulators.  Some examples of solid-state devices include: Thermoelectric modules: Transfer heat from one side to another by consuming electrical energy Accelerometers: Respond to a wide range of...
