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

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

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

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

The Gray Wolf also known as the “Canis lupus was known to be the most largest nondomestic member of the dog family” (Fritts‚ Steven H). “They have lived in every type of habitat except from the tropical forests and the most arid deserts” (Fritts). From the moment gray wolves are born to the moment they die‚ they are viewed as a danger to humans. “Ever since the 19th and 20th century

In Reaction 1‚ the mass of the pre-cut copper wire was measured with watch glass on the analytical balance‚ the mass was recorded using as many significant figures as possible on Table 2. The copper wire was bended into a circle and laid flat on the bottom of the 250 mL beaker. Inside the fume hood‚ 4mL 16M of HNO3 was added into the 250mL beaker that contained the copper wire. The copper wire was completely dissolved by swirling the beaker. The observation was recorded in Table 3. For Reaction 2

With the abundance of social issues included in The Wire‚ some may find it surprising how there is still room for a “vast and complex social network” of characters (Potter198). The show switches the narrative point-of-view often between the police‚ politicians‚ drug dealers‚ corner kids‚ teachers and other

11th D Flame Test Intro: The flame test is a procedure used by chemists to identify the presence of specified metal ions‚ based on the color the flame that appears along with it when it ’s heated. Our flame test was in lab class‚ where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced‚ the second one was to identify unknown metals based on their flame color

In episode 3 of The Wire‚ there are a lot of characters that seem to know nothing more than selling drugs and making money. However‚ in this scene starting at 10:41 and ending at 12:41 shows that these characters are bit more complex and two sided than we are shown. This scene starts with a very fast pan of the pit area until the camera finds D’Angelo. This pan of the courtyard shows how unsafe it is‚ and how the characters are being watched and how they should watch their backs. The pan of the

The close up shot of the wire illustrates to the audience that extreme actions are undertaken to create an atmosphere in which she can belong. The barbed wire indicates that intruders aren’t allowed to enter her surroundings as they could severely impair her sense of place‚ thus highlighting that indeed belonging and place are
