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 generates a magnetic field. This magnetic field interacts with the…
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 of a car door lock…
How does a MOSFET have lesser conduction losses power consumption than a BJT in switching applications? ing your question about conduction losses – a mosfet channel resembles a resistor, so the losses correspond to the current x squared resistance. a…
What makes sensors work? The main purpose of an electronic sensor is to convert the physical parameters of the environment into electrical parameters [ie. voltage or current] different sensors work in different ways. A temperature sensor may consist of a…
Is MOSFET a bidirectional device or unidirectional device What is a clear explanation about this? all fets are bidirectional devices. mosfet is a symmetrical device which means that source and drain can be interchanged (if the body is short-circuited with…
Why do we need of biasing? Think of it as a check valve that controls the flow of water. close, no water flow. open a little, flow of water, now you understand. a transistor must be biased to provide a…
Why do we use an insulating layer between the gate electrode and the channel region for a MOSFET? The length of the channel and the current flowing from the source to the drain are controlled by the electric field applied…
What is a solenoid? any conductor wound in the form of a spring is called a solenoid when used in a circuit to generate a constant magnetic field. when the conductor coil is rather used as an impedance to resist…
How to test a thyristor how to test a thyristor (scr): get a dc bank power supply with adjustable output voltage and current limit. For example, 0-30vdc 0-5a set the power supply to approximately 30vdc, short-circuit the output wires and…
What is rectifier circuit? Please read the rectifier, AC, frequency, diode and resonance before knowing this. it can charge the battery by supplying DC power to my battery to charge as well as any device requiring DC power any circuit…
Why do old vacuum tube amplifiers sound so rich compared to modern Transistor FET amplifiers? tl; dr : google on the euphonic distortion. Vacuum tube amplifiers have a higher gain in mid frequencies. Generally used, especially in social situations, amplifiers…
How electricity genrate? Electricity is one of many forms of energy. if a load is stored in a place, its effect is limited, but if the load finds a network and begins to sink, the current has more properties and…
Why do you need a current limiting resistor to drive an LED if the LED draws only as much current as it requires? to save the led from the high voltage. resistance causes the voltage to drop. the limiting resistor…
