What is transformer? Which motor is used in mixer grinders? Differentiate between AC and DC current? Which frequency is used in India and USA? What is different types of motor?

Question

Accepted Answer

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

Transformers are used to increase or decrease voltage levels in electrical circuits.
Mixer grinders typically use universal motors, which can run on both AC and DC power.
AC current periodically changes direction, while DC current flows in one direction only.
In India, the standard frequency is 50 Hz, while in the USA it is 60 Hz.
Different types of motors include DC motors, AC motors, stepper motors, and servo motors.
