The same h parameter model is used for npn and pnp transistors because gain is gain. It does not matter if you are using a negative or a positive system. So long as you are consistent in your calculations, you will get the correct results. In an NPN transistor operating in class A, if you increase the base current by increasing the base voltage, you will increase the collector current which decreases the collector voltage. In a PNP transistor operating in class A, if you increase the base current by decreasing the base voltage, you will still increase the collector current, which will increase the collector voltage.
What else can I help you with?
Is a transistor a small electronic switch?
A transistor is used to switch electronic signals.
What circumstances led to the invention of the transistor in 1947?
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
Can a transistor be used with 220volt dc?
yes...........
Does a cathode ray tube resemble the tubes used in transistor radios?
Transistor radios have NO tubes. They have (guess what) transistors.
What is base resistance Rb?
Base resistance (Rb) is the resistance seen by the base terminal of a transistor when analyzing its behavior in a circuit. It is a parameter used to model the input impedance of the transistor and is crucial in determining the biasing and signal amplification characteristics of the transistor circuit.
Why h parameter model is not used for high frequency analysis?
The h-parameter model assumes linearity and is mainly used for low and mid-frequency analysis where the transistor operates in the active region. At high frequencies, the parasitic elements like the capacitances associated with the device cannot be neglected, leading to inaccurate results. High-frequency models like the hybrid-pi model or S-parameter models are more suitable for analyzing transistors at high frequencies.
Why you use h parameter?
Type your answer here... TO DECREASE THE COMPLEXITY . ANSWER: h parameters are used to analyze small signal behavior o a transistor.
What is a vacuum tube used for?
The same things a transistor is used for.
Why h parameter are not used for transistor mode at high frequency?
finding h parameters involves open and short circuits which is difficult to obtain at high frequencies due to stray inductance and capacitance
Why and when should programmers use a constant reference parameter?
when we use that parameter as a global parameter and we used that parameter through out the program without changing

it is a transistor used in IR TOGGLE SWITCH. :-)
Why a transistor is used as a amplifier and switch?
transistor has 2 output 1 and 0 so can be used as a switch
