What is the difference between a CB amplifier and CE and emitter-follower?
I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
What is power gain of an amplifier having input gain 20watt and output of 20mwatt is?
The power gain of an amplifier having an input of 20W and an output of 20mW is 0.001. Expressed in decibels, that is a gain of -30db. (log2 0.001 * 3)If you meant an output power of 20MW (mega instead of milli), the gain is 1,000,000, or +60db.
Pioneer a335 amplifier and the volume control resistor has broke i am woundering since they don't sell it no more what the equvilant of the resistor act1047 is?
If you cant find a spec sheet, take out a multi meter, set it to ohm mode and measure the thing. If its a variable find something in the same range, if its fixed you should be able to find a suitable replacement. If its a big resistor make sure you get a power resistor and not a standard ceramic one.
Does the power amplifier amplifies the power?
the final stage of a power amp is a current amplifier in a bipolar design and a voltage amp in a FET design.

Can a power amplifier amplifies the power?
Question: Can a power amplifier amplify the power? An amplifier can amplify the voltage or the current. Power can be converted to heat.
How does power amplifier differ from a conventional voltage amplifier?
A voltage amplifier does not have to supply significant current bur a power amplifier does.
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
How can I get amps for my guitar amplifier?
You can get amps for your guitar amplifier by purchasing and connecting a separate amplifier unit, also known as a power amplifier, to your existing guitar amplifier. This will allow you to increase the overall power and volume output of your guitar amplifier.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
May power amplifier a voltage amplifier?
A power amplifier may also boost voltage; in audio equipment, power amplifiers often have a dial on the front that is used to control the input voltage gain. A simple power amplifier is composed of a single transistor; this type of configuration cannot provide voltage amplification as well. A voltage amplifier stage is needed. So the above example of an audio power amplifier is actually a voltage amplifier stage, followed by one or more power amplifier stages.
How do you find power generated in a resistor?
The power generated in a resistor is converted into heat. and that can be power which is converted into heat is the product of the voltage across the resistor and, current passing through the resistor. or the product of square of the current and the resistance offered by the resistor.
What does an amplifier do for a subwoofer?
An amplifier will power your subwoofer so they can work.
What are the basics of how flashlights work?
You need a conductor, power source and a resistor. You need a conductor, power source and a resistor. You need a conductor, power source and a resistor.
