OHM’S LAW INTRODUCTION Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points‚ and inversely proportional to the resistance between them provided the temperature remains constant. The mathematical equation that describes this relationship is: where V is the potential difference measured across the resistance in units of volts; I is the current through the resistance in units of amperes and

battery. As a form of energy‚ light can be emitted through a variety of processes. These processes may include 1. Incandescent lighting works through the emission of light due to heat‚ this is the process of an ordinary light bulb. 2. Both fluorescent and phosphorescent lighting is the emission of light in response to radiation energy.

Steve Jobs has been labeled a visionary by many‚ and rightfully so. Though he may not be the tech celebrity that he once was‚ nor is his name any longer so strongly associated with the basic‚ commonplace components of software and hardware design that he helped to pioneer and that computer users the world over take for granted‚ the charismatic‚ passionately counterculture chief executive officer of Apple Computer was once the most important individual in Silicon Valley and even today dictates the

The bright lines come from mercury gas inside the tube while the continuous spectrum comes from the phosphor coating lining the interior of the tube. After doing a little bit of research on the internet‚ I discovered that fluorescent light bulbs contain a mixture of inert gases (usually argon and neon) together with a drop of mercury at low pressure‚ so that some of the mercury atoms form a gas in the tube. I also learned that the inside of the glass tube is coated with a phosphor

"Electrical Energy Consumption" Sustainability and electricity Where does electricity come from? Most people use electricity and see it as something that is infinite and probably don’t give a second thought about its source. This is quite understandable‚ considering electricity looks clean; it doesn’t cause any noise pollution or direct air pollution. The fact is that most electricity is produced by burning coal‚ and the use of nuclear power plants. Simply stated‚ the more electricity used‚
