The History of the Electric Guitar The desire to increase the sound of the guitar existed long before the development of electrical amplifiers and speakers. Musical performances in the 19th century were characterized by ever-larger concert settings and ensembles. Musicians needed louder and more powerful instruments‚ which became possible by using new materials and designs. The introduction of steel strings in the 19th century meant not only greater volume‚ but greater tension on instruments

Electric Charge Lab John Doe Physics 1130 Oct 26th‚ 2010 Objective In this lab we will investigate some properties of electric charge‚ conductors‚ and insulators using everyday objects. Theory A charged object is any object that has an excess of negative or positive charge. Most objects are neutrally charged and we don’t normally experience their charge properties. Rubbing objects together and transferring some charge from one to the other is one way to create charged objects. Like charges

Lesson 11. Topic “Heating effect of an electric current”. Grammar material: Articles. Text: “Heating effect of an electric current”. The production of heat is perhaps the most familiar among the principal effects of an electric current‚ either because of its development in the filaments of the electric lamps or‚ may be‚ because of the possible danger from overloaded wires. As you know‚ of course‚ a metal wire carrying a current will almost always be at a higher temperature than the temperature of

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this
