Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper wire is due to the properties

Man on Wire VS Grizzly Man Have you ever wanted to do something as exciting as walking on a wire or watching bears in their natural habitat. Philippe Petit and Timothy Treadwell both dedicated characters‚ which put their life at risk. Philippe a childish daring man considered walking on the wire in one of the largest building in New York. Timothy a passionate reckless man driven to observe bears in their habitat in many different places. Both characters have a lot in common‚ mainly both characters

How does the length of a wire affect its resistance? Introduction: This first report in Physics will show the investigation of how the length of a wire affects its resistance. For starters I will go through the main definitions‚ to get a better knowledge of what is going to happen. However I will plan it out first to show each step of how I started‚ and then go into detail about the results and what the investigation on a whole has showed me. I shall then conclude my findings and present them with

THE FINANCIAL CRISIS OF 2007- 09‚ EFFECT ON THE ECONOMY OF JAPAN Japan is among one of the most rapidly growing economies in the world. The economy is primarily dependent upon the service sector which is highly developed followed by the manufacturing and industry sector. The country is rich in new and innovative technologies which benefit it to endeavour in the competitive era. The overall GDP of Japan in the year 2012 was $5960 billion and the purchasing power parity was $4.617 trilllion representing

current when the length of wire changes‚ so I then can work out the resistance. I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. I will not go above 1m or below 0.20m because it may be too long that they resist so much current that the wire burns‚ or the length of the wire is so small that it doesn’t resist any current at all. The length of the wire will be changed by moving the crocodile clip across the wire on a ruler. The independent

Verify your expression by using the experimental results obtained. If your results do not show the expected relationship‚ explain why. In order to derive an expression for the magnetic field B at a point of distance r‚ from an infinitely long wire that carries a current I‚ we can refer to fig. 10. From

In this photo‚ including myself‚ there are five people. I am on the far left‚ and one of the four persons on the inside of a barbed wire gate located at a motel about thirty miles south from Tegucigalpa. I carried a large bottle of water and wore an aged Redskins’ football t-shirt. These four people on the inside of the gate are in their night wear and etc. The one person behind the gate is wearing semi presentable clothes (a tucked in blue collared shirt‚ a buckled white pair of cargo shorts and

a certain few of Cohen’s that stand above the rest. Songs that were hits‚ and songs that in fact helped shape the period of time they were created in. "Suzanne"‚ "Bird on the Wire"‚ and "So Long‚ Marianne" are a couple of these elite creations of Cohen’s mind. During this paper I will be analyzing the song "Bird on the Wire"‚ interpreting its meaning and explaining what it is saying. This song was one of Cohen’s most famous songs‚ and was very influential during the ’60’s- a time of turmoil and unrest

An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting
