Investigating the resistance of a wire. Planning For this investigation there are a number of variables that can be chosen to change or keep the same‚ these are: · Length of the wire. · Diameter of the wire. · Type of the wire. · Temperature of the wire. Scientific explanation. All electrical conductors resist current through them to some extent. This is resistance and this affects the size of the current flow. The main dependence of resistance are: § It’s Length. § It’s Thickness

others around them. In Robert Greys poems‚ this is demonstrated a numerous amount of times‚ through the use of metaphors‚ similes‚ descriptive language and many more language techniques. The Poems that this is most evident in are "Flames and Dangling Wire"‚ "Late Ferry". The speaker contemplates the fragility of nature and how urbanisation is used as a justified means to ignore the consequences

for survival for them and their family? Victor is a Mexican boy from the novel Crossing the Wire whose family is impoverished. He is forced to go to America in hopes of being able to provide for his family. Poverty badly hurts Victor’s family‚ and Victor will have to get a job in America or Victor and his family will be doomed. Poverty impacted Victor’s family negatively. In Chapter 2 of Crossing the Wire‚ Victor thinks “And Rico didn’t know what it felt like to be hungry‚ really hungry‚ the way

Most people in today’s society do not stray far from what is perceived as normal‚ but some people dare to do extraordinary things. People such as Philippe Petit featured in the documentary Man on Wire and Timothy Treadwell featured in the documentary Grizzly Man. These two individuals share many similarities in regard to what they are willing to do to achieve their goals. They also share differences in regard to how they think and how they respond to fame. I intend to delve deeper into their characters

Sociological Character Analysis: Randy From a sociological perspectives as to why Randy gets in trouble so often this could be related to his race‚ his lack of real family and growing up in the system‚ his lack of education‚ and his lack of money. In the Wire you see the teachers and principal use this against him by threatening to call his foster mom unless he gives them the information they want‚ such as‚ who has been graffitiing school property. His lack of money is what reluctantly drives him to do

Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat

Wind the wire around the PVC pipe. Fix the ends of the wires to the insulation tape. Remove about 3 cm. of insulation from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter

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
