An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.

What are 2 things that cancel an accidental?
There's 3 types of accidentals, which can cancel eachother, so there's really 3 things that cancel an accidental: Sharp, Flat, Natural
Conditions for faithful amplification?
1. Signal to noise ratio should be low at the amplifier outlet. (Vaccuum tube amps are best.) 2. No distortion at the output due to the amp being overdriven. 3. Impedence matching at the input and output.
Difference between amplifier and power amplifier?
Voltage amplifiers are genrally used to amplify voltage signals to a certain db and amplification is a linear process. In power amplifiers it is not required to amplify voltage it is not significant and genraly equal to input voltage. It is significantly used to produce a large current at the output.
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
How many syllables are in amplify?
3 syllables are in the word amplify. :)
What damages a rectifier?
Rectifiers are electrical parts, all electrical parts are rated for 3 things. 1) voltage 2) current 3) temperature Exceed any of these things and the electrical part will fail.

Is there electrical equipment can sum 3 dc signals to get 1 output signal?
An operational amplifier can sum an arbitrary number of signals and produce a single output signal.
What are the 3 things that converts chemical energy to electrical energy?

Can a PlayStation 3 be a amplifier for a car?
No.
How do you replace your amplifier in your 2004 Kia Optima?
My amplifier was in the trunk on the passenger side wheel well. 3 nut and it comes right off.
What 3 things is safe working practices designed to help prevent?

How are microphones able to amplify sound?
There are 3 steps. Sound waves move a microphone diaphragm back and forth and microphone translates movement to electrical signals. Then recorder encodes electrical signal . Finally a player reintripets the electrical signal using electricity to move speaker cone. All are major componets theys take signal in one form and put in another. In the end sound signal is translated back to original form.
What is a Scaling amplifier?
3-63A SCALING AMPLIFIER is a special type of summing amplifier with the output signaldetermined by multiplying each input signal by a different factor (determined by the ratio of the input-signal resistor and feedback resistor) and then adding these products
