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

meters of varnish insulated copper wire with diameter 0.5mm PVC pipe- 300mm length 3- 1.5 volt batteries with casing 3- jumper wires with crocodile clips Multimeter Scissors Infrared Thermometer 1 roll of insulation tape Procedure 1. 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

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

almost fulfilled her motivation for life. The “Meaning of Life” as Frankl sees it is that it can only be defined by the own person. Nobody can have the same meaning to their life‚ every human is different. “ For the meaning of life differs from man to man‚ from day to day and from hour to hour. What matters‚ therefore‚ is not the meaning of life in general but rather the specific meaning of a person’s

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

What was the lesson that you learnt from Carl Frederickson? Why? • The movie “up” is such a meaningful story. This story talks about two main characters Carl Frederickson and Russell . In past‚ Carl was a 9years old boy who has idolize famous explorer- Charles Muntz. he admires him. one day‚ carl befriends a girl named Ellie‚ she is Muntz’s fan too .So they become good friends.
