Electronics in easy words.
The differences between UJT (Unijunction Transistor) and FET (Field-Effect Transistor) lie primarily in their construction and operating principles. A UJT is a three-terminal semiconductor device with a unique structure consisting…
The pinch-off voltage in a JFET (Junction Field-Effect Transistor) refers to the gate-source voltage at which the channel between the source and drain terminals becomes completely depleted of charge carriers…
A generator used to charge a battery is typically designed to produce direct current (DC) output, suitable for charging batteries commonly used in automotive, marine, and off-grid applications. These generators…
NMOS (N-channel Metal-Oxide-Semiconductor) and PMOS (P-channel Metal-Oxide-Semiconductor) transistors are types of MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) with different channel doping types. NMOS transistors have an N-type channel (electron conducting), whereas PMOS…
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) can operate in two main modes: enhancement mode and depletion mode, each serving different purposes and having distinct characteristics. Enhancement mode MOSFETs require a positive…
An AC generator, also known as an alternator, operates on the principle of electromagnetic induction. This principle states that when a conductor (such as a coil of wire) moves through…
A switch is a fundamental electrical device used to control the flow of electricity within a circuit by opening or closing contacts. Its primary use is to enable or disable…
In a circuit breaker, a trip coil and a close coil serve distinct functions related to the operation of the breaker. The trip coil is an electromagnet that, when energized,…
To increase your knowledge of electronic devices and circuits, it’s essential to start with foundational understanding and gradually progress to more advanced concepts. Begin by studying basic electronics principles, such…
REF (Restricted Earth Fault) and SEF (Sensitive Earth Fault) protection are both methods used to detect and respond to ground faults in transformer systems. REF protection is used to detect…
