What else can I help you with?
What happens when high input signal is given to pnp transistor?
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
What is a transistor that is normally on with no applied signal?
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
What is hie for a transistor?
hie is input impedance when signal applied at its base.
When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
Why transistor is called transfer of resistor?
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
Can transistor be used to increase the strength of an ac signal?
Yes, a transistor can amplifiy an a.c. signal.
How is current amplified in a transistor?
Transistor increase the strength of a weak signal from the base
What is unmodulated signal from a transistor is called?
When the out from a transistor is the exact replic of the input signal then it is called unmodulated signal i e. there will not be any change in frequency voltage power etc
What happens when high input signal is given to pnp transistor?
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
What is the work of transistor?
The work of a transistor is to amplify the input signal to get high output value.
Why is a transistor an active element?
Transistor is an active element because it can amplify the signal applied.
What is a transistor that is normally on with no applied signal?
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
Why you add a positive voltage to the ac signal to allow a transistor to amplify ac signal?
It depends on how you bias the transistor. If you ground the emitter, which is very common, you will need to offset the input signal so you can amplify the full voltage swing.
Which of these is not a type of signal used to send information through electricity?
transistor
