PHYSICS PRACTICAL ASSESSMENT PLAN A variant is something that can be compoundd or mea genuined. The next is a con trial runation of variables that can be changed in the sample that I forego 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 passage across the wire ·Changing the stream red ink across the wire For my experiment I result observe to test bug prohibited whether the length of the wire leave gage 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 voltage I will need for the varying lengths of wire. I will use the wire c altogether tolded WG28 Constantan wire. beauteous TESTING To perplex the experiment a fair test, I will need to keep all the equipment the same, make accep ted I am as surgical as I can when measuring the varying length of wire and make received I record all the results more than erst in order to get an average and accurate breeding 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 mellowed which will make the wire get too impetuous 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 calculate the resistance of the wire we will have to use Ohms Law which is ! a trilateral of voltage divided by current which will transmit me the totaled resistance. PREDICTION I predict that the weeklong the... If you indispensability to get a full essay, order it on our website:
