Q: What does a transformer actually transform voltage current or energy?
A: A transformer transforms voltage and current.
Q: Is it correct to say that a generator produces energy?
A: A generator is a machine that converts mechanical energy into electrical energy.
Q: How does transformer induction transform current?
A: The transformer induction principle is based on the fact that a current-carrying conductor will create a magnetic field around it. If this conductor is then placed in a magnetic field, the magnetic fields will interact and a force will be exerted on the conductor. This force can be used to generate a current in the conductor.
Q: Why does a transformer require AC?
A: A transformer requires AC because it needs to create a magnetic field in order to work. The magnetic field is created by the changing magnetic flux, which is caused by the changing current in the coils.
