Called a transformer! Not called amplification if a transformer is used. (it is being done with solid state now so Transformers are not being used in Power supplies much anymore) Look at the power pole that is a transformer and it steps the high voltage down to house hold voltages. Works both ways. The highest wires on a power pole can but in the hens of thousands of volts. The transmission lines are in the hundreds of thousands of volts.
If you are talking about a weak signal or radio signal then it is a amplifier, made from electronics, transistors, tubes, resistors, capacitors and coils. Integrated circuits (IC's), just have those in them much smaller. The circuits are the same. Look it up. There are probably thousands of ways to wire an amplifier.
What else can I help you with?
Can a current transformer be used for current amplify?
transformers cannot amplify!
What are the two kinds electricity?
Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.

Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
How is AC current generated?
AC voltage, making AC current available, may be generated in several ways: * AC generator driven by * Steam turbine * Diesel motor * Petrol motor * Water turbine * Inverter from a DC source
Can you amplify the AC in your data center using an AC transformer and how?
Yes, the AC current can be amplified by using Step-down transformers, but one problem is the AC voltage will decrease with Step-down transformer.
What is the function of an AC transistor in electronic circuits?
An AC transistor in electronic circuits is used to amplify and control the flow of alternating current (AC) signals. It acts as a switch or amplifier to regulate the voltage and current in the circuit, allowing for the manipulation and processing of AC signals for various applications.
Can a current transformer be used for current amplify?
transformers cannot amplify!
What type of component can amplify the current in a circuit?
A transistor, working in active mode, can amplify a current in a circuit.
What is difference between ac and DC amplifier?
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
What type of signal to amplify by using differential amplifier?
ac and dc
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.
Does a fan run on a dc current or ac current?
AC
How can you block ac current?
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
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.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Is it true a transistor changes alternating current into direct current?
Not usually. A transistor is an amplifier, that can be used as a switch. If set up correctly it can be used to rectify AC current (i.e. convert it into DC), however it will need a capacitor to smooth the DC current (i.e. keep the voltage constant or nearly the same). What is typically used is a rectifier, a small circuit consisting of one or more diodes.
