Any system you design will have an input and an output. The output will connect to the input of another system which will load it, so when you are designing any system you have to consider how loading it will effect the circuit performance.

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.
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.
What is hie for a transistor?
hie is input impedance when signal applied at its base.
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 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
Why the base bias Q-point in transistor circuits changes with temperature?
why we use base resistor in emitter bias

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 is emitter biasing?
Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.
How do you use a transistor?
A transistor is an electronic component that can be used as an amplifier or a switch. It has 3 connections: base, collector, emitter. It conducts electricity via the emitter to the collector only when the right voltage is applied to the base. As an amplifier, the amount of current it conducts at any instant will vary in a manner which depends on the instantaneous value of the varying voltage that is applied to the base.
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".
