How to test a thyristor?
How to test a thyristor (SCR): Obtain a bench DC power supply with adjustable output voltage and current limit. For example 0–30Vdc 0–5A Set the power supply to around 30 Vdc…
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…
Why do we use an insulating layer between the gate electrode and the channel region for a MOSFET?
A layer of silicon oxide (SiO 2) typically grows on a silicon substrate and a metal or polysilicon layer is deposited over it. If you observe, this acts as a…
Why do we need of biasing?
Bias: is a term from no less than 400 years, which means “oblique or diagonal line”. It is not an error of assessment, it is a preference. If you research…
Is MOSFET a bidirectional device or unidirectional device What is a clear explanation about this?
The MOSFET is a symmetrical device in which the source and drain can be interchanged (if the body is not short-circuited to the drain or source). The MOSFET transistor is…
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…
How does a MOSFET have lesser conduction losses power consumption than a BJT in switching applications?
MOSFETs are unipolar devices, i. H. There is only one type of carrier in action, generally electrons. BJTs are bipolar devices, i.e. H. Both electrons and holes conduct electricity within…
What is an electric motor?
Any device using the interaction between an electrically generated magnetic field and another magnetic field generated electrically or naturally to function. According to this definition, for example, the electric solenoid…
How does an AC motor work?
How does an AC motor work? There are two main aspects of an AC motor stator and a rotor, the supply is supplied (three-phase or single-phase) to the stator that…
How do transformers work?
How do transformers work? The transformer has a laminated iron core and only operates with an AC power supply on an electromagnetic conductor. example: the primary coil has 1200 turns,…
