The basics of solid state devices.
A device frequently used in solid-state equipment such as lighting dimmers and variable speed controls is the silicon controlled rectifier (SCR). As shown
The basics of solid-state devices.
Another workhorse of electronic equipment is the transistor. There are two types of transistors commonly used: PNP and NPN. As shown in Fig. 1, the PNP
