The value of r when a transistor is biased to cut off is -?
Collector-to-Emitter resistance is high when the transistor is biased off.
What is the base spreading resistance?
base spreading resistance is the resistance which occur at the base of transistor dis is becoz of varying base voltage
How a transistor transfers resistance?
The input current of transistor is approximately equal to output current .Suppose in common base configuration the emmiter current is approximately equal to collector current if neglect the very small value of bae current.Even though the input resistance is not equal to output resistance,the currents are same ,so we can reliase that the transistor transfers resistance to get same currents at both ends.
Working of transistor as an oscillator?
A transistor is often referred to as an oscillator because of its ability to transfer resistance. it can also switch off and on repeatedly, mimicking an oscillator.
What is the Effect of collector resistance in emitter follower circuit?
Colector resistance in an emitter follower circuit serves to place a limit on how much current can be supplied by the transistor. Often, the resistor is sized so that a short circuit in the load does not cause the transistor to fail.
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.
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.
What do you mean by base-spreading resistance?
Base-spreading resistance refers to the resistance that exists in a bipolar transistor due to the spreading of the base current into the collector region. This resistance can limit the transistor's high-frequency performance and impact its overall efficiency. Reducing base-spreading resistance is important for improving the speed and performance of a transistor.
Why transistor is called so?
transistor. This word is a blended form of transfer of resistor. The legs of transistor (collector, emitter,base) transfer the resistance. So it is called as transistor
How does using a transistor with a different beta affect the operation of the common emitter amplifier?
Gain, in the common emitter amplifier, is beta (hFe) or collector resistance divided by emitter resistance, whichever is less. Substituting a different beta (hFe) transistor will affect gain, if hFe is less, or increase stability and design margin, if hFe is greater.
The value of r when a transistor is biased to cut off is -?
Collector-to-Emitter resistance is high when the transistor is biased off.
Why is a Junction transistor so named?
In a transistor a current from low resistance input circuit is transferred to a high resistance output circuit with almost unchanged magnitude. This results in a power gain. Infact the name 'transistor' is coined from 'transfer resistor'
What is the r-parameters of transistor?
r parameter is resistance parameter
What is the characteristics of transistor?
the name itself we can say that the transistors are used to transfer from low resistance to high resistance.
What is the base spreading resistance?
base spreading resistance is the resistance which occur at the base of transistor dis is becoz of varying base voltage

What is swamping resistance?
(Electronics) Resistor placed in the emitter lead of a transistor circuit to minimize the effects of temperature on the emitter-base junction resistance and its resistance is called swamping resistance.
