Why transistor is so difficult to understand
Why transistor is so difficult to understand? intuition of the operation of a bjt is more difficult than the intuition of a mosfet but the equations of the model of…
Category: How to Guide
This category cover topics of electronics “How to Guide”. Basic theory of electronics and question answer with how tech works with easy way with example. it also cover electrical fundamental like current, voltage and its calculation, some circuit design, device use and benefits etc.
Does a transistor amplify current or voltage
transistor is a current-controlled device. current amplification only in common basic mode, only voltage amplification occurs, in common collector mode, only current amplification occurs, in common emitter mode, amplification of…
How does AC work? Does this mean the electrons swing back and forth along the wire at the frequency of the current flowing?
The ac current does not flow in the same direction. electrons in the wire (and other components) simply move back and forth. You know a joke where everyone is lining…
Can transistors work with ac
Can transistors work with ac? Yes. the exact function depends on how you connect the transistor. in addition, the frequency changes the gain of the transistor. use a power bjt…
Why are PNP transistors used
Why are PNP transistors used? We use pnp mainly for convenience and to simplify certain circuits. npn is a device used to reduce current, while pnp is a device used…
What is a Q point of a transistor
Q point of a transistor? The point q of a circuit describes the output level when the input is short-circuited or disconnected. that is to say that the transistor (s)…
Why do we use biasing in transistor
The polarization of the transistor is to switch the glass, which facilitates the passage of the current from the source to the drain, or from the transmitter to the collector….
Why are transistors called transistors
Why are transistors called transistors? it is nothing more than a semiconductor device through which currents and voltages of the desired magnitude can be obtained. It can be used as…
What controls the gate in a transistor
What controls the gate in a transistor? inside a microchip, transistor gates are usually driven by other transistors but they could also be driven by transistors directly or directly connected…
Can we use a transistor as a rectifier
Can we use a transistor as a rectifier? yes, but because of the relatively low current limits, the base junction can handle many transistors, it might be better to use…
