Resistivity of a wire experiment results
WebThis experiment can be used to teach about the idea of validity of scientific results. Results may be rendered invalid if an uncontrolled factor affects the results. In this case, the temperature of the wire is a factor which affects measurements of its resistance. Discuss how this can be taken account of. WebResistivity Experiment. Aim: To find out whether or not temperature affects the resistivity of a metal wire when put into oil. Plan. To find out whether or not that temperature does have an affect on the resistivity of a wire when placed into water I will take one piece of wire (iron) and put it into a circuit with a power supply, a voltmeter and an ammeter. The …
