A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

Why feedback is important in system control? Systems approach: input (sensors like thermostats), process (microcontrollers), output (actuators like heaters). Feedback ensures accuracy and stability.

This SCR phase control works much like the common TRIAC dimmer, but has numerous advantages including increased current capability, robustness and absence of minimum voltage “snap-on.” A complementary ...
