Electricity

Characteristics of Ohmic and non-Ohmic Conductors

Some atoms contain loosely attached electrons. These electrons can be made to move easily from one atom to another. When these electrons move freely along a path, a current of electricity is created. Electrons can only flow freely in materials that conduct electricity. A Conductor of electricity is a substance that allows electricity to flow […]

What is alternating current (AC)

Most students of electricity begin their study with what is known as direct current (DC), which is electricity flowing in a constant direction, and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with definite positive and negative terminals), or the kind of charge generated by rubbing certain […]

Energy Workers Make a World of Difference

Energy workers are a part of the huge network of people that make our country as great as it is today. Even Jeff Landry himself a member of congress said “the most valuable resource in the gulf of Mexico is not the oil and gas under the waters; it is the men and women willing […]

Load Shedding Crisis in Pakistan

Electricity is a basic need for sustaining human life. We cannot even imagine how our lives would have been if electricity was not discovered. Looking at it from an economic growth perspective of a country, the creation of energy is very essential. Pakistan however has been facing an acute shortage of electricity for many years […]

The New Era of Energy at UMass

The University of Massachusetts Amherst Building Authority recently closed the old coal power plant which is adjacent to campus center way (Main Campus).This was the only source of the utility system at UMass for many decades , and then scheduled to be replaced in the early 1970s by Tilson Farm steam plant which was dilemma, […]

Electric Current

“Battery-Resistor”: Check “show battery” and “show cores”, watch what happens, adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery, label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The electrons are […]

Current, Voltage, Resistance and Ohms Law

Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere, symbolized by A. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. […]

Static Electricity

The purpose of this experiment is to explain the different aspects of static electricity, including effects of electrical charges on small-uncharged objects, electrical attraction and repulsion, creation of electrical charge, practical uses of electrical charges, and measurement of electrical force between electrical charges. Findings Electric current is the flow of electric charge. Some materials become […]

Cigarette filter as glue

Nowadays, we are encountering severe floods that lead to electrical power shut down. So we have come up to an applied research which is entitled “The Feasibility of Making a Mechanical Generator through the impact of rain water” that can help each one of us. Our materials were examined to measure its ability to provide […]
