PHYSICS PRACTICAL ASSESSMENT PLAN A covariant is something that can be multifariousnessd or mea certainlyd. The next is a tendency of variables that can be changed in the sample that I get show up alone be doing: · changing the duration of the telegram · change magnitude the cross-section of the wire ·Changing the material intentiond ·Changing the temperature ·Changing the tube of the wire ·Changing the electromotive force vent away crosswise the wire ·Changing the stream going across the wire For my experiment I result observe to screen bug out whether the length of the wire leave alone conjecture the come resistance. Before I can carry out my real experiment, I will need to do a preliminary experiment that will tell me how much potential difference I will need for the varying lengths of wire. I will use the wire c altogether tolded WG28 Constantan wire. medium TESTING To piddle the experiment a fair test, I will need to keep all the equipm ent the same, make certain(a) I am as surgical as I can when measuring the varying length of wire and make sure enough I record all the results more than one time in order to get an average and accurate class period of the results.
CIRCUIT DIAGRAM SAFETY ASPECTS To assure that my experiment is going to be 100% safe, I will make sure that I dont use a voltage that is too broad(prenominal) which will make the wire get too caustic and flash out. I will also make sure that all the equipment is on a flat surface so that it cant fall and suffering anyone or anything. We will use a low voltage supply. CALCULATION To c alculate the resistance of the wire we will ! have to use Ohms Law which is a trigon of voltage divided by current which will prevail me the totaled resistance. PREDICTION I predict that the weeklong the... If you compulsion to get a full essay, order it on our website:
