if it is an A.C supply we can amplify by Transformers, transistors, voltage doublers and voltage multipliers.
but if it is an D.C supply, the voltage can be amplified only by means of choppers (i.e buck converters, boost converters and buck boost converters)

How can you amplify?
You amplify by getting a microphone and speakers. Once you have played into the microphone i then amplifies into the speaker and a louder volume is created
Is amplify mindware program of bharti vidyapeeth university pune approved by AICTE?
yes Amplify Mindware courseware is approved by AICTE. For further details visit the website http://www.bvuadit.com/
What type of signal to amplify by using differential amplifier?
ac and dc
Why Positive Feedback can't use in Amplifier?
because +feedback amplify noise also.it amplify the noise to input ratio by[1/(1-G.H)]. WHERE g=open loop gain H=feedback gain
Why you need op amp?
Opamp or Operational Amplifier is used in both analog and digital circuits.As its name implies it can do mathematical operations like addition,subtraction of two applied voltages (used along with resistors).It can also perform differentiation and integration of applied voltage functions.Other than performing mathematical operations it can also perform logical operations like comparing two voltage levels and on the basis of it it can give high or low output i.e. it can be used as a comparator.It can amplify or scale down an applied voltage level by a constant scaling factor by choosing the required resistors.
What are the propeties of transistors?
A: It amplify voltage depending on configuration
How can a transister can amplify the voltages?
When it's assembled into a circuit with other components and a power supply, atransistor can be used to amplify changes in voltage, but it can't amplify voltages.
Is it possible to amplify voltage and current gain at the same time?
yes
What is the function of a coil pack?
To amplify the voltage going to the spark plug
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.
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.
Why you add a positive voltage to the ac signal to allow a transistor to amplify ac signal?
It depends on how you bias the transistor. If you ground the emitter, which is very common, you will need to offset the input signal so you can amplify the full voltage swing.
How do you amplify a square signal?
To easily do that all you need is a higher voltage level or the level that you desire . square waves usually are states of [1] or rail voltage and on[0] saturation voltage. to linearly amplify these square waves you will need a hi band pass amplifier . Possibly 50megahz or so
What 3 things does an electrical amplifier amplify?
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 do copper coils do?
amplify voltage, the more wraps in the coil the more voltage I think. others may improve this answer but thats what i have found to be true.
Can you use transformer in place of amplifier?
A transformer is a passive device while an amplifier is an active device. a transformer can amplify voltage but never power WHILE AN AMPLIFIER CAN amplify power's can you use it sure withing the limitation of the transformer and only to amplify volts.
What is the simplest way to convert capacitance to voltage?
If it is a variable cap, apply AC signal to the capacitor as per its specifications.This is done because the variation in the voltage gives a corresponding current output due to the charging and discharging of capacitor. Then a Trans-impedance amplifier can be used to convert this input current to voltage. Current amplifier can be used to amplify the current at the input of the trans-impedance amplifier. Similarly a voltage amplifier can be used at the out put of the trans-impedance amplifier to amplify the voltage output.
