How Does The Legnth Of A Wire Affect Resistance In A Circuit? Physics Investigation Aim: To measure how the length of a wire affects the amount of resistance when an electrical current is passed through it. Background Information: What is an electrical current When a full circuit is created (i.e. a continuous loop has been made connecting the negative end of an electrical source to the positive) it creates a path for electrons to pass through. These electrons need a "push"

Study Guide‚ Chapter 8: Production and Distribution of Electricity Essay Questions: 1. Where are the big electric power plants in your state and what type of fuel do they use1? What is the primary fuel source used overall in your state? Massachusetts hosts three liquefied natural gas import terminals‚ one at Everett and two offshore of Gloucester (my hometown). Massachusetts generated 68 percent of its electricity from natural gas and 11 percent from coal in 2011. http://www.eia

use static electricity to funtion 1. Van de Graaff generator When the motor is turned on‚ the lower roller (charger) begins turning the belt. The belt is made of rubber and the lower roller is covered in silicon tape‚ the lower roller begins to build a negative charge and the belt builds a positive charge. Silicon is more negative than rubber so the lower roller is receiving electrons from the belt when it goes over the roller. The positively charged atomic nuclei‚ try to move toward the

Static Electricity Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons‚ electrons and neutrons. Protons have a positive charge (+)‚ electrons have a negative charge (-) and neutrons have no charge at all‚ they are neutral. Atoms normally have the same amount of electrons and protons‚ making them neutral and having no charge. When rubbing things together‚ electrons can move from one atom to another‚ resulting in some atoms having extra

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

Electricity and Magnetism History Electromagnetism Originally electricity and magnetism were thought of as two separate forces. This view changed‚ however‚ with the publication of James Clerk Maxwell’s 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions‚ all of which have been clearly demonstrated by experiments: 1. Electric charges attract

History of Electricity Our knowledge of electricity has started from very humble beginnings when you look at where we are today. Electricity has been around for as long as humans have. When lightning strikes ancient people may not have understood what it was or why it happened‚ but they at the very least witnessed it happen. Nature acted as a sort of catalyst to spark the curiosity of early people. It was only until sometime between 624 BC and 546 BC where an understanding of electricity began to

There are a number of independent power producers that contributes significantly in electricity generation in Pakistan. For years‚ the matter of balancing Pakistan ’s supply against the demand for electricity has remained a largely unresolved matter. Pakistan faces a significant An Overview of Electricity Sector In Pakistan challenge in revamping its network responsible for the supply of electricity. Due to an unrealistic power tariff‚ high inefficiencies‚ low payment recovery and the
