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 types of materials against each other. As useful and as easy to understand as DC is‚ it is not the only “kind” of electricity in use. Certain sources of electricity (most

ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

Ionic compounds do not conduct electricity in solid form but their aqueous solution conduct electricity. Why? Or Common salt does not conduct electricity but its aqueous solution conduct electricity. Why? Ans. Ionic compounds (e.g.- Common salt) have strong electrostatic

A World Without Power If you can‚ imagine a world without the simple‚ everyday privilege to have electricity in your home. Nikola Tesla is the single person responsible for giving this ability to the common world. Without Nikola Tesla‚ the world would be very different due to his inventions. His contributions pushed the world forward because of his alternating current‚ his wireless‚ and his energy related inventions. Nikola Tesla is not very well known for most of his inventions‚ even though

Line & Beyond The materials‚ which allow electric current to pass through them‚ are good conductors of electricity. On the other hand‚ materials‚ which do not allow electric current to pass through them easily‚ are poor conductors of electricity. You know that metals such as copper and aluminum conduct electricity whereas materials such as rubber‚ plastic and wood do not conduct electricity. Conductivity of Liquid To test whether a liquid allows electric current to pass through it or not‚ we

Thomas Edison’s contributions to society through the science of electricity are undeniable and extremely significant. However‚ in the competition between his promoted DC electricity and George Westinghouse’s AC electricity‚ Edison employed some seemingly questionable motives in an attempt to succeed in the three-fold motive; enhance his reputation as a leading scientist‚ reap the profits that would come‚ and protect his established reputation which would be ‘dented’ by losing. Edison’s reputation

a connection between electricity and magnetism. * When a current was switched on through a wire‚ it made a compass needle turn so that it was at right angles to the wire. * The current had produced a magnetic field strong enough to cause the compass needle to turn. Additional effects due to experiment * It was already known that an electric current in a wire has a heating effect‚ and may cause the wire to glow. This showed that the three phenomena of electricity‚ heat and light were

INTRODUCTION Nikola Tesla was born on July 10‚ 1856 in Smiljan‚ Lika‚ which was then part of the Austo-Hungarian Empire‚ district of Croatia. His father‚ Milutin Tesla was a Serbian Orthodox Priest and his mother enjoyed great fame throughout the countryside for her skill and originality in needlework‚ and doubtless transmitted her ingenuity to Nikola; though it naturally took another and more masculine direction. Tesla was educated at the Realschule‚ Karlstadt in 1873‚ the Polytechnic Institute
