Question

10. Transformer works on the--------​

Answer 1

Answer:

Transformer works on the magnetic induction principle

Explanation:

Transformers, in the simplest form, are electromagnetic devices that are used to transform power.Transformers consist of three main pieces: A core (typically ferromagnetic (iron), and two individual sets of wire coils. The coils are referred to as the primary and secondary winding. When applying AC current to the primary winding of the transformer, the coil creates a pulsing magnetic field. The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy. Once the magnetic field reaches the secondary coil, it forces the electrons within it to move, creating an electric current via electromotive force (EMF).It was discovered that using a solid core was not ideal because a lot of energy was lost in the form of heat due to something called eddy current. To help with this, the cores are now made of laminated sheets of iron to help disperse the heat more evenly and prevent energy loss.

A transformer’s main function is to step-up or step-down the voltage from the primary to the secondary winding. This is done simply by adjusting the ratio of coils on one side to the other.
