What else can I help you with?
What is swamp resistor?
Resistor placed in the emitter lead of a transistor circuit to minimize the effects of temperature on the emitter-base junction resistance.
How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
How to draw NOT gate using NPN transistor?
RTL logic: NPN transistor. Emitter grounded. Input connected to base through a resistor. Vcc also connected to base through a resistor. If the input is high or open, the transistor is on. If the input is low, the transistor is off. Connect a resistor from Vcc to the collector. The collector is the ouput. You have to play around with resistor values to setup your fan-in and fan-out properties.
Why do you have to connect a resistor to collector of transistor?
Type your answer here... to properly bias the junction for current flow thru the transistor. The voltage potential must be different on the base than the collector
What will happen when terminals base and emitter gets interchanged in a transistor?
It won't work.
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

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.
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.
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 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 to draw NOT gate using NPN transistor?
RTL logic: NPN transistor. Emitter grounded. Input connected to base through a resistor. Vcc also connected to base through a resistor. If the input is high or open, the transistor is on.

Why transistor is named so?
What?In May 28, 1946, a survey conducted by Bell Labs offered “a discussion of some proposed names”Among them was "transconductance/transfer varistor".So the question repeats the common mistake that it was "transfer resistor".
Why the base bias Q-point in transistor circuits changes with temperature?
why we use base resistor in emitter bias
What does resistor means?
A transistor has three leads, called the base, the collector, and the emitter. The voltage of the base (in relation to the ground) determines whether and how much current flows from the collector to the emitter. An NPN transistor can be off, meaning that there is no (or very little) voltage from the base; partly on, meaning that there is some voltage from the base; or saturated, meaning that it is receiving full voltage from the base. A saturated transistor allows the current to flow from the collector to the emitter unopposed; a partly on transistor provides some resistance; and a transistor that is off provides full resistance. A PNP transistor is similar to an NPN transistor except it performs the opposite function: when it is saturated, the current is fully resisted; when there is no voltage from the base, the current is not at all resisted; and when it is partly on there is some resistance. In sum, a transistor controls the flow between the collector and the emitter based upon the voltage of the base. this is carbage. a transistor is basicaly two diodes back to back base being common TO BOTH DIODES because of inpurity doping on purpose at the depletion region the transistor will control the current flow on the other diode. Once it reaches saturation both diodes conduct therefore current can flow in BOTH DIRECTIONS ACROSS IT.
