- Q1. Tell me about your self
- Q2. What is electricity
- Ans.
Electricity is a form of energy resulting from the existence of charged particles (such as electrons or protons) either statically as an accumulation of charge or dynamically as a current.
Electricity is the flow of electric charge through a conductor.
It is a form of energy that powers various devices and systems.
Electricity can be generated from sources such as coal, natural gas, nuclear, hydro, wind, and solar.

- Q1. How so supply to dc convert
- Ans.
To convert AC to DC, a rectifier is used which converts the alternating current to direct current.
A rectifier is used to convert AC to DC.
There are different types of rectifiers such as half-wave rectifier, full-wave rectifier, and bridge rectifier.
Rectifiers use diodes to convert the current.
The rectifier circuit filters out the AC component and provides a smooth DC output.
Examples of rectifiers include power supplies

It can also be used in homes and offices to provide backup power to computers, routers, and other electronic devices.
UPS systems come in different sizes and capacities, ranging from...
- Q2. How the transformer work
- Ans.
Transformers work on the principle of electromagnetic induction to transfer electrical energy from one circuit to another.
Transformers have two coils of wire, a primary coil and a secondary coil, wrapped around a magnetic core.
When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.
The voltage in the secondary coil is proportional to the numbe...
