affects the resistance of a wire. Reworded: I am going to investigate if changing the length of a wire changes its resistance. I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)‚ the thickness of the wire‚ and the temperature of the

bravery. In his inaugural address‚ President John F. Kennedy challenged his country with‚ “And so‚ my fellow Americans‚ ask not what your country can do for you -- ask what you can do for your country.” One obvious way of serving America is joining one of the forces of the United States Military- Air Force‚ Army‚ Navy‚ and Coast Guard. Out of all four branches‚ the American armed forces has a rough estimate of 1‚420‚000 people‚ and that number grows all the time. When signing up for the military‚ these

Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes the electrons harder to

because the electrons would bump into more atoms‚ the longer the wire which is like using up its fuel. Material – different materials inherent resistances as they have more or less atoms in them already. Thickness – Thickness affects resistance because the thicker the wire the more paths the electrons have to avoid the atoms. Therefore the cross sectional area is larger so there is less resistance. Temperature – The hotter the wire is the more energy the electrons have to flow faster. Why do we

What does it mean to be a citizen of the United States? I would define a citizen as someone‚ who was born in‚ or to a certain place‚ who is guaranteed certain rights in the place that they were born in. Citizenship in the United States means that a person is a legally recognized member of the nation. Each citizen has equal rights under the law. All citizens have certain rights‚ privileges‚ and responsibilities. Americans who are not citizens have many of the same rights‚ privileges‚ and responsibilities

Problem Does temperature affect the resistivity of different sized copper wires? Hypothesis I think that the resistivity will increase with higher temperatures because with higher temperature‚ resistivity is higher due to the fact the atomic lattice structure increases. Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement

Bird on the Wire by Cohen Leonard is a personal song that talks about the great challenges of humanity. The poem first starts off saying that people are very free but still confined by comparing us to birds on a wire. Then the song talks about making mistakes and hurting people but always trying make it up. I believe that this is a sad song about feeling out of luck and down‚ and always trying to find yourself from within. I personally really enjoyed the message the second verse was trying

Daniel Osherow ENGR 1301 5 December 2012 Copper Wire Sizes (EE) The diameter of a copper wire is measured by using a system called the American Wire Gauge also known as AWG. This system has predominantly been used in the United States and Canada since 1857. Using this measurement the cross-sectional area of a gauge is able to be found. We then use this area to determine the wires current carrying capacity. The gauge numbers for wire and diameter values work inversely‚ as when one increases the

RECENT TRENDZ IN POWER GENERATION POWER GENERATION FROM ROAD SPEED BREAKER AND FROM SHOES (Recent way to produce power) ABSTRACT: Man in his lifetime‚ uses energy in one form or the other. In fact whatever happens in nature‚ results‚ out of the conversion of energy in one form or the other? The blowing of the wind‚ the formation of the clouds and the flow of water are a few examples that stand testimony to this fact. Of late‚ erratic and perfunctory usage
