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

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.
How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
What is rt in electronics?
I believe that is resistor transistor technology TTL transistor transistor logic
How do you interface a relay to a microprocessor type 89C51?
you cannot directly interface a relay to a microcontroller, you need a buffer circuit in between the two, you can use a NPN transistor BC 547, connect the controller pin directly to the base of the transistor (since there is an internal 10k pull up resistor inside the controller no need of any base resistor). Connect the transistors emitter to the gnd & the collector to the relay coil, the another end of the relay coil goes to the supply, check this link for complete information http://www.dnatechindia.com/index.php/Tutorials/8051-Tutorial/Relay-Interfacing.html
What is pnp resistor?
PNP stands forÊjunction transistor having an n-type semiconductorÊ setting between a p-type semiconductor as emitter and a p-type semiconductor as a collector.

Circuit diagram for fixed bias circuit?
need to use BC107 transistor which has three terminals base, collector and emitter........ collector is connected with 6.8k ohm resistor other end of this resistor is connected with 3.7 ohm resistor and it is connected to the base of the transistor which is already connected to a capacitor of 1 micro F and a positive of function generator......and in the output side i.e in the collector and emitter side connect the 1 micro F capacitor and 10 kohm resistor and connect the CRO...... then other to the ground.......
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 transistor so named?
Transistor stands for "Transfer Resistor". (Resistor of transference)
What is the full form of transistor?
The fullform of transistor is transfer resistor.
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
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".
What is self biasing a transistor?
if a transistor resistor is connected to the emmiter .
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
What is rt in electronics?
I believe that is resistor transistor technology TTL transistor transistor logic
