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 –…
How does a PTC relay with capacitor work?
PTCÂ relay A PTC relay means positive temperature coefficient is a starting device for refrigerator compressors. It is responsible for providing power to the start winding for a brief moment to…
Difference between NMOS PMOS and CMOS transistors
NMOS is constructed with the n-type source and drain and a p-type substrate, while PMOS is constructed with the p-type source and drain and an n-type substrate. In an NMOS,…
How is FET a voltage controlled device
How is FET a voltage controlled device? the voltage applied between the gate and the source controls the drain current (id). which means you use the voltage to control the…
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 are some of the advantages that a bipolar junction transistor has over a MOSFET?
Advantages that a bipolar junction transistor has over a MOSFET? The collector current follows an exponential function of the base-emitter voltage very precisely and over a wide range (can be…
What is IR photodiode?
An IR sensor is basically a device consisting of a pair of an IR LED and a photodiode, collectively referred to as photocouplers or optocouplers. The IR LED emits IR…
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 capacitor in refrigerator?
The refrigerant condenser is responsible for maintaining the proper functioning of the appliance. The capacitors store an electric charge and then release it every time the refrigerator motor has to…
