# New Electrical Projects for Electrical Engineering Students

### new electrical projects

new electrical projects Electrical engineering is an engineering stream that comprises study and understanding about electricity and electronics. The main work of electrical engineers is to distribute energy for different devices. They have to use their knowledge and skills of electrical engineering for solving various technical problems. Some of the works that an electrical engineer is capable of doing on some specified electrical devices or products include developing GPS systems and airline navigation systems; designing power generating and transmitting system like a power plant of a wind farmhouse, and so on.

Electricity

So what is electricity and where does it come from? More importantly, why is carpet, socks and a doorknob a bad combination? In its simplest terms, electricity is the movement of charge, which is considered by convention to be, from positive to negative. No matter how the charge is created, chemically (like in batteries) or physically (friction from socks and carpet), the movement of the discharge is electricity.

Current

This flow of electrical charge is referred to as electric current. There are two types of current, direct current (DC) and alternating current (AC). DC is current that flows in one direction with a constant voltage polarity while AC is current that changes direction periodically along with its voltage polarity. Thomas Edison and Alessandro Volta were pioneers in DC current and wrote much of electricity’s history. But as societies grew the use of DC over long transmission distances became too inefficient. Nikola Tesla changed all that with the invention of alternating current electrical systems. With AC it is possible to produce the high voltages needed for long transmissions. Therefore today, most portable devices use DC power while power plants produce AC.

Ohms Law

The most fundamental law in electricity is Ohm’s law or V=IR. The V is for voltage, which means the potential difference between two charges.
