What is an NPN transistor used for?

The most commonly used configuration of the transistor is the NPN transistor. We also found that the bipolar transistor intersections can be biased in one of three different ways –…

What is PSM in relay?

In the field of electrical engineering, a relay is a relay device designed to trip a switch when an error is detected. The first protection relays were electromagnetic devices based…

What is the pinch off voltage for a JFET?

JFET Pinch off voltage “Pinch-off” is not locked. During pinch-off operation, the discharge current does not drop to zero. Instead, the Id current becomes constant, remaining relatively independent of the…

What is a starter PTC?

A PTC (Positive Temperature Coefficient) relay is a starting device for refrigeration compressors. It is responsible for feeding the starter winding for a short time to help start the refrigerator…

What is the use of a capacitor?

Capacitors play an essential role in the stable operation of digital electronics by protecting the noise sensitive microchips from the power signal that can cause abnormal behaviors. Decoupling/By-Pass Capacitors The…

What is capacitor and its unit?

A capacitor is a passive electrical component with two terminals that stores electrical energy in an electric field. The effect of a capacitor is known as capacity. While there is…

What is a solenoid?

A magnet is a coil of insulated wire that is wound on a rod-shaped form made of solid iron, solid steel or iron powder and generates a magnetic field when…

What makes sensors work?

Most sensors use radiation such as light or laser, infrared waves or other waves such as ultrasonic waves to detect objects and changes in their surroundings. They can do this…
