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,…
Why is enhancement MOSFET preferred over depletion MOSFET for switching purposes?
Why is enhancement MOSFET preferred over depletion MOSFET for switching purposes? The source of the mosfet is very often connected to the power rail. therefore, the amplification type gates are…
How to use thyristors?
How to use thyristors If you buy a thyristor, it must have given you the data sheet in which the voltage limit, the current limit, the performance charts, etc. have…
What is a relay?
What is a relay? relay that detects the fault and the information given to the c.b. sequence of operation: relay-c.b-isolator: Relays are switches that open and close circuits electromechanically or…
Why does the overall resistance of a circuit decrease as the resistors are connected in parallel?
Why does the overall resistance of a circuit decrease as the resistors are connected in parallel? in order for the voltage to be constant on all parallel paths, it is…
