In an ideal transformer the power in equals the power out there is no gain. In an ideal amplifier the power out equals the Gain *Power In.
An ideal transformer transforms energy at a ratio of its windings.
For example an ideal 1:10 ratio transformer (step up) would convert a 10Volt input at 10amps to a 100Volt output at 1Amp. Or conversely an ideal 10:1 ratio transformer (step down) would convert a 10Volt 10Amp input into a 1Volt 100Amp output.
Since Power = Voltage * Current we can see the power in equals the power out in an ideal transformer.
In an ideal amplifier the power out is greater than the power in. This is defined as the gain of the amplifier.
An ideal amplifier with a Voltage gain of 10 would take a 1Volt 1amp signal and amplify it into a 10Volt 1 amp signal.
An ideal amplifier with a Current gain of 10 would take a 1Volt 1Amp signal and amplify it into a 1Volt 10 amp signal.
Since Power = Voltage * current we can see the power in is less than the power out showing a gain in power.

Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
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.
Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
What is the formula for gain in a power amplifier that has a step down transformer?
A: there is no formula the gain of the amp is just reduced by the transformer turn ratio minus efficiency or loss. the transformer is for isolation and impedance matching
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 transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
Does DC amplifier exist?
Yes, it's called a Transformer. Definitely the wrong answer. DC on a transformer is certainly going to blow it up. The answer is yes unless capacitor coupling is involved
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 does transistor acts as an amplifier?

What is the basic difference between transistor as an amplifier and a step up transformer?
The output power of an amplifier is greater than its input power, whereas the output power of a transformer is almost the same as its input power. In other words, an amplifier increases acts to increase power, whereas a transformer only increases voltage.
Which coupling give higher gain in case of amplifier?
Transformer coupling
What is the definition of audio-frequency transformer?
An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
Which coupling gives the higher gain in case of amplifier - a Capacitor coupling b Impedance coupling c Transformer coupling?
