In Transformers, it is the no.of turns of winding which is constant is use to merely step up or down voltage or current.
The magnetic flux is linked with the coils due to current flowing through the coil and nothing more.Hence Transformer is a passive device.
What else can I help you with?
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?
When transformer is used in step up mode then we can use transformer as amplifire
How does transistor acts an amplifier?
When transformer is used in step up mode then we can use transformer as amplifire
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 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?
transformer coupling
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
