investigatory project focused on the energy stored on the flashlight which has been charged for the exact hour. The energy stored at the flashlight could either produce light or electrical for the phones to charge. We researchers have guessed that the energy that is stored in the flashlight has a capacity to charge a cellphone.

INTRODUCTION Alessandro Giuseppe Antonio Volta is known as the scientist that founded the electric age. He was an Italian physicist pioneer that contributed greatly to the development of the battery. Alessandro Volta was born in Como‚ Italy in 1745. He attended a public school; in 1774 he was appointed professor of physics at the Royal School in Como. His first invention was an electrophorus; a device that produced static electricity. In 1776-77 he devoted his time to chemistry‚ studying atmospheric

Leaf electroscope.. It is a simple apparatus with which the presence of electric charge on a body is detected (see figure). When metal knob is touched with a charged body‚ some charge is transferred to the gold leaves‚ which then diverges due to repulsion. The separation gives a rough idea of the amount of charge on the body. If a charged body brought near a charged electroscope the leaves will further diverge. If the charge on body is similar to that on electroscope and will usually converge if

Electrophoresis Electrophoresis is a method to separate body substances; this technique isolates them by placing the sample in an electric field. This phenomenon was first observed in 1807 by Reuss from Moscow State University who noticed that a constant electric field caused clay particles dispersed in water to migrate. It is caused by the presence of charges of the surface of the particle and the surrounding fluid. This was perfected in 1937 by Arne Tiselius (1902-1971). It is used in forensic

Irodov Problem 3.7 As shown in Figure 1‚ the charges are located in at the four corners of the square ABCD whose diagonal is of length 2l. Since the point Xis located at a height of x units from the plane of ABCD along its central axis‚ the distance of X from any of the corners A‚B‚C and D is . The electric field strengths due to each of the four charges located at corners A‚B‚C and D are given by‚ The vertical components of EC and EB will cancel

Explain why you think they move apart and what might affect how far apart they get. They move apart due to the fact they get charged when rubbing them on your hair and the same charge is on both balloons. The more you rub them on your hair the more charged they will become making

An electric field surrounds electrically charged particles and time-varying magnetic fields. The electric field depicts the surrounding force of an electrically charged particle exerted on other electrically charged objects. The concept of an electric field was introduced by Michael Faraday. The electric field is a vector field with SI units of newtons per coulomb (N C−1) or‚ equivalently‚ volts per metre (V m−1). The SI base units of the electric field are kg⋅m⋅s−3⋅A−1. The strength or magnitude
