How Electricity Gets To Your HouseIt's always there whenever you flip a switch or plug in a cord, but electricity has to travel a long way to get to your house. The current is sent through transformers to increase the voltage to push the power long distances. The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines. It travels through distribution lines to your neighborhood, where smaller pole-top transformers reduce the voltage again to take the power safe to use in our homes. It connects to your house through the service drop and passes through a meter that measures how much our family uses. Kids, never touch a service panel!  It is only to be operated by your parents or a professional.
Electric power systems around the world are currently undergoing substantial changes in their structure and rules of operation.
Debates and controversy continue with regard to the exact form that restructured electric power systems should take.
Some commentators continue to argue that this restructuring process has not produced the intended improvements in system efficiency while at the same time it has complicated efforts to ensure the reliability of system operations and the efforts of traders to protect themselves against financial risks. This course will cover topics essential for understanding key issues currently surrounding the restructuring of electric power systems both here in the U.S.
You are strongly encouraged to attend and participate in class, but role will not be called. Some exercises will be individual assignments, and some exercises will involve assigned teams. There will be TWO MIDTERM EXAMS held during the semester, as well as a COMPREHENSIVE FINAL EXAM.
The first midterm exam is scheduled for Monday, September 19 in our regular classroom at our regular time.
The final exam will be a comprehensive closed-book exam covering all required materials from the first day of classes through the final day of classes. Absence from either a midterm exam or the final exam will result in a grade of zero unless the instructors agree there are verified extenuating circumstances such as a major medical emergency.


Feel free to contact the instructors during their office hours, class meetings, or through email if you have any questions or concerns.

Inventor Thomas Edison believed that direct current electricity was better than alternating current. Electricity is a type of energy that involves the movement of electrons along a conductor, such as a wire.
In the late 19th century, another scientist, Serbian-American engineer Nikola Tesla, worked on developing AC because could transfer different amounts of power. Another difference between AC and DC involves the amount of energy that each one can carry.
How we can use the electrical current to overcome the magnetic field on a pipe when we want to weld? What happens if you chop the ground rod off that is located outside the house and that is buried approximately six feet down?
DC loses more energy when traveling further due to what happens when applying the magnetism along the wire steadily and not using the magnet that is rotating. If I want to check the voltage coming out of a battery charger with a volt meter, do I check AC or DC volts? In general taking a step forward and a step backward implies that we are in the same position. In power electronics how is converting power ac to dc (rectifier) and dc to ac power(inverter) used and given motor(load)? I want the brief explanation and the use of the flux inside the soldering iron and its nature. In fact, the power plant where your electricity is made might be hundreds of miles away!All the poles and wires you see along the highway and in front of your house are called the electrical transmission and distribution system.
Federal Energy Regulatory Commission) are in the process of revising the entire regulatory framework within which electric power systems operate, with fiduciary responsibility for protecting against risks to national security. In the latter case, either the course grade will be determined on the basis of other work completed (if sufficient work has been completed) or the student will be asked to retake the course at a later time. In the search to create electrical energy, scientists discovered that electrical and magnetic fields are related. Instead of applying the magnetism along the wire steadily, he used a magnet that was rotating.


Every battery is designed to produce only one voltage level, and that voltage of direct current cannot travel very far until it begins to lose energy. When the magnet is oriented in one direction, will the electrons flow towards the positive, but when the magnet's orientation is flipped, did the electrons turn as well?
It requires a high voltage with reduced current, just like AC does, but the losses are much less than with AC. Today, power plants all across the country are connected to each other through the electrical system (sometimes called the "power grid"). A magnetic field near a wire causes electrons to flow in a single direction along the wire because they are repelled and attracted by the poles of the magnet.
When the magnet was oriented in one direction, the electrons flowed toward the positive, but when the magnet's orientation was flipped, the electrons turned as well.
AC voltage from a generator in a power plant can be bumped up or down in strength by another mechanism, called a transformer. A power plants produces electricity at a very high voltage so that it can travel great distances.

The reason that AC was initially used was because the change from high voltage DC to AC was very difficult to do reliably, and really wasn't feasible until the 1960's. If one power plant can't produce enough electricity to run all the air conditioners when it's hot, another power plant can send some where it's needed.
Alternating current (AC) is when the electrons flow in both directions — one and then the other. This is how DC power from a battery was born, a development that is primarily attributed to American inventor Thomas Edison's work and promotion during the 19th century.
The voltage must be reduced, however, before the electricity reaches homes and other buildings that use it to power appliances, machinery and other devices. Batteries produce direct current, and electrical power grids that provide electricity to homes and other buildings use alternating current.
AC also can be changed to DC by an adapter, such as the kind used to power the battery on a laptop computer.
