What is A or C biasing?
The three standard forms of analog amplifier biasing are:class A - the amplifier is biased in the center of its linear operating range, this is the most linear but least efficient type of amplifier (because the transistors or tubes are always conducting, even when there is no signal to ampliify).class B - the amplifier is biased at the cutoff point, this is an efficient amplifier but is only linear if operated as a push-pull amplifier (because the transistors or tubes are in cutoff and not conducting when there is no signal and through one half of every cycle, a class B push-pull amplifier has two sections that operate on alternate halves of the cycle).class C - the amplifier is biased in hard cutoff so that only the peaks of the input signal are amplified, this is the most efficient amplifier (because the transistors or tubes may be in cutoff and not conducting for more the 85% of the time) but it is not capable of linear amplification. An amplifier biased as class C is only suitable for use in RF transmitter power stages, where a resonant LC tank circuit will be excited into oscillation by the output of the amplifier and complete the missing parts of the cycle.There are other forms of biasing (e.g. class AB) analog amplifiers that get some of the advantages of two of the standard forms. There are also forms of amplifiers having other nonstandard classes (e.g. class D) that are not analog amplifiers, but instead operate by amplifying pulses.
Why do guitar rockers choose tube amplifiers instead of transistor amplifiers?
A: TUBE AMPLIFIERS are operating at higher voltage which makes the dynamics of amplitudes more desirable. Other then that there is no other reason. tube amplifiers are bulky heat generating components efficiency poor and frequency limited.
What are typical values of input impedance and outoput impedance of ce amplifiers?
Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
Why a turbocharger is not used in a petrol engine?
They certainly are. Using them together with carburetted engines can be a bit tricky, and usually the compression has to be lowered when compared to a naturally aspirated engine.
Which is more efficient loaded or unloaded circuits?
Efficiency is typically associated with minimizing losses in a circuit. If you have no load you couldn't compute efficiency. If there is a load you need to determine what you are trying to measure. For example, in an incandescent light bulb a lot of power is wasted in heat. So if light is what you are looking for an incandescent bulb isn't very efficient. A compact fluorescent would be more efficient. However, if you were using a light bulb to power an "Easy Bake" oven it would be more efficient.
Are 2 channel monoblock amplifiers less efficient than 1 channel monoblocks?
Depends on the class ratings class a/b are less efficient class ds are more efficient but usually monoblocks amps even if it is "2 channel" are wired to just one set of positive and negative input on the inside of the amp hence the term monoblock
How can someone sell their Class D amplifiers?
Someone can sell their Class D amplifiers by putting a listing up on eBay or Amazon. Amazon is the best choice because your item will be more likely to sell.
Which amplifier has more efficiency than class b amplifier?
Class C amplifier.. A class D amplifier is more efficient than class B, and is more efficient than class C as well.
How loud are car amplifiers?
Car amplifiers can be as loud as those which have more than 1000 watt power. The Loudest TL-1021 series from WIKIO are some of the loud car amplifiers. Audio Assault also comes out with car amplifiers of 1000 W.
Is every mosfet an amplifier?
No. Mosfets are used for their switching capabilities more then amplification purposes if anything. for Pulse width modulation, power supplies, for certain frequencys, and smoothing out power sources, signals, and PWM can be used in class D amplifiers as well to have a very good efficiency.
How does steam power compare to power create by running water?
Steam power is more efficient.
What all do you need to put more bass into a car?
Amplifiers and better speakers. But amplifiers are a must.
Is a longer or shorter exhaust more efficient for performance in a dirt racecar?
The short exhaust should be more efficient and increase power.
Is the power amplifiers amplify the power?
A: There is a misconception of understanding of terms here. A power amplifier is called that because it has capabilities to derive power from it .It does not create power it actually uses more input power then the power delivered, In other words it has a decrement in efficiency

How efficient are natural gas power plants compared to other types of power plants?
Natural gas power plants are generally more efficient than other types of power plants, such as coal or oil-fired plants. They can convert a higher percentage of the energy in natural gas into electricity, making them a more efficient and cleaner option for generating power.
Why is ce amplifiers preffered over cb amplifiers?
yes because efficiency and application specify is more improve
