This is a vague question. Which transistor, and what is the make of the FM trasmitter? What do you really want to do, design an FM transmitter or repair an existing one?

What is a polarized semiconductor component?

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.
The device which acts like an NPN and a PNP transistor connected base to base and emitter to collector is?
Triac
Why transistor have 4 wire?
The transistor is a three layer (or two junction) device, emitter, base, and collector (or other designations for variations such as FET's). Each layer is connected to a terminal. Three layers - three terminals.
Which Capacitor should be connected in one direction?
The electrolytic capacitor should be connected in only one direction.
What is darlington configuaration?
A Darlington pair uses two transistors connected to behave as a single transistor with a very high current gain (beta). Transistor-1 has its collector connected to the collector of transistor-2. Transistor-1 has its emitter connected to the base of transistor-2. The base of transistor-1 with the emitter and collector of transistor-2 is used as a single transistor.
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.......
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
How do capacitors work in conjunction with transistors?
hi am just a newbie in a electronics but with the little knowledge i got, well, when a capacitor is connected with a transistor, the circuit can act like a multivibrator i.e charge and discharge to the transistor base as in timer circuit.When the capacitor is connected to the power supply e.g battery,it will charge to an extent that the charge in it will be equal to the charge the base of the transistor will need to turn the transistor on,say 0.7v and when the transistor is on then the collector will start work.NOTE:this process happens in milli seconds and also that i might be wrong somewhere so lets research more to get the answers.this is for my fellow newbies in ELECTRONICS.

Why is the collector of a transistor connected to the base or heatshink?
Because most of the heat buildup occurs in the reverse biased collector-base junction where Ic = Ie + Ib flows.
A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased This transistor can be used as a power amplifier?

What type of transistor do I need to replace an NPN D227 G-615 It takes a 9V battery input at the emitter an IC's output at the base and the collector drives a 8ohm 0.2w speaker.?
Answer The D227 is a general purpouse NPN transistor and not realy critical, one of the following, is ideal replacements for the D227 transitor BC337, BC635 and BC637 There is an error in the question, a NPN transistor's Collector is always connected to the positive of the supply and not the Emitter, an easy way to remember it "the collector, collect the current (stream of electrons) and emit it at the emitter". It is correct if the speaker is connected between the positive of the battery and the collector, although it can be connected between the emitter and the negative but for many reasons it is not good practice.
Working of npn transistor?
N-p-n transistor is made by sandwiching thin layer of p-type semiconductor between two layers of n-type semiconductor. It has three terminals, Emitter, Base and collector. The npn transistor has two supplies, one is connected through the emitter base and one through the collector base. The supply is connected such that emitter-base are forward biased and collector base are reverse biased. It means , Base has to be more positive than the emitter and in turn, the collector must be more positive than the base. The current flow in this type of transistor is carried through movement of electrons. Emitter emits electrons which are pulled my the base as it is more positive. these end up in the collector as it is yet more positive. In this way, current flows in the transistor. Transistor can be used as an amplifier, a switch etc.
