Ultimate Trivia Quiz On Transformer In Physics Quiz

Let’s start the quiz

A transformer is an electrical machine used to change the voltage of an alternating current that has the same frequency. Which is used to convert the voltage of the alternating current to the same frequency, that is, the transformer with low voltage strong alternating current in high voltage weak current, or high voltage weak current in low voltage strong current Transmits at the same frequency. The transformer is made of a magnetic circuit consisting of two characteristic coils, called primary coils and secondary coils. When the primary coil is connected to the alternating current supply, the alternating flux is formed in the plated core and a reversible force is induced in the secondary coil when this flux is connected to the secondary coil. This action is caused by induction between the two coils. Let's know more about Transformer In Physics.
