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.
What else can I help you with?
Why different transistor have different resistance?
Because they are different transistors. Resistance among their internal diodes is one of the main features of a transistor.
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
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.
Why transistor is called transistor?
Because in this device the resistance between two terminal respectively collector and emitter is changed by changing the base voltage that is it transfers the resistance between emitter and collector therefore it is called as TRANSISTOR. (TRANSFER OF RESISTOR)
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.
Why different transistor have different resistance?
Because they are different transistors. Resistance among their internal diodes is one of the main features of a transistor.
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
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.
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.
