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.
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.
Why does a CE amplifier have a high gain?
GAIN is a function of load current but basically a small current in the base will make a big change of collector current therefore making a transistor a voltage amplifier as opposed to a current amplifier
What is the difference between an amplifier and a booster?
an amplifier is electronic equipment that increases strength of a signal and a booster is voltage regulation in (DC) direct current electrical power circuits. Basically an amplifier increases strength and a booster regulates voltage.
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.
What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Why transformar is not called an amplifier?
because it does not amplify anything, it transformers voltage and current. "amplifier" implies that input powe is increased at the output by increasing the voltage or current, or both. With a transformer, power in equals power out minus losses. The power "gain" of a transformer is always less than 1, if you want to think of it in amplifier terms.
How do you wire computer fan into car amplifier?
Cant. Fan on computer runs on house current (power) which is AC and the car has a DC (direct current) power system.
What is a common application of a cc amplifier?
current amplifier
How you differentiate amplifier and transformer?
A big difference. A transformer converts power into more useful means of transportation or matching to the end results.Pincoming = IPVP = Poutgoing = ISVS.giving the ideal transformer equationVs/VP= Ns/NP=IP/Isthen as the outgoing voltage of the transformer increase, the outgoing current will decrease. An amplifier adds power. For example, voltage amplifier add voltage (amplify) independent the amplifier current.
Is there any amplifer which will work without an external current source?
An amp with no power supply? No. Can't be done. An amplifier increases the current of the input signal, and to do so it needs power to do it with.
What is one common application of a cc amplifier?
current amplifier
