Can a step-up transformer be used as an amplifier?
In this article, we are going to know Can a step-up transformer be used as an amplifier or Not?
As a Step Up Transformer can increase the amplitude of the applied voltage or in the other word a Step Up Transformer can increase the amplitude of the voltage waveform and an Amplifier also can increase the amplitude of the voltage waveform. So you may think that a Step Up Transformer can be used as an Amplifier-that's wrong.
Why we cannot use a Step Up Transformer as an Amplifier described below.
Why we need Amplification?
Actually why we need amplification?. A Transducer or any other devices which can produce signals as our requirement. This type of devices produces very weak signals which cannot drive speakers and other output devices. In this cases, we need the amplification of these weak signals that means an increase of power of these signals.
Which device can increase power without taking any auxiliary power?
There is no device which can increase the power of any signals without taking any auxiliary power source. If any device can increase power without taking any auxiliary power that means it generates energy. As we know that energy cannot be created or destroyed it can be transferred one form to another form. So this type of device not available.
Why a Step Up Transformer cannot be used for Amplification?
A Step Up Transformer cannot use for Amplification because if you are an Electrical Engineering student then you already know that a Step Up Transformer can increase only voltage, not power as it does not take any auxiliary power source. But we need to increase the power of the weak signals. So, for this reason, a Step Up Transformer cannot use for Amplification.
Now you may think that a Transformer cannot increase power but how an Amplifier can increase power. There are many types of amplifier available and each type of amplifiers has different working. So I have tried to give a basic idea of working an amplifier in the below section.
How an Amplifier can increase Power?
An amplifier is a device which can increase the magnitude of the power of the weak signal which is given as input by using an auxiliary power supply(DC supply). Actually, an amplifier generates a new output signal which has a power of high magnitude according to its input signal by taking an auxiliary DC power supply.
