Using the equipment, carefully construct the following circuit. Do not turn on the power yet. The switch on the power pack should only be switched on for very short periods while readings of the meters are made. Leaving the power on too long may change the temperature of the wires too much and spoil your results. The power pack was set to the lowest setting (~2V). The switch was closed momentarily to check that the the needle of both meters deflected in the right direction. A table to record results was prepared with two columns, one to record the ammeter readings and the other the voltmeter readings. The switch was again closed and the readings on the ammeter and voltmeter for the lowest power setting were noted and recorded in the table. This was repeated for each successively higher setting from the variable power supply until the maximum setting was reached (12V). The results were readings on the ammeter and voltmeter were recorded in the table for each available setting from the power supply. Important: The power was only switched on briefly to allow the readings of the meters to be taken and then the resistor was allowed to cool between each measurement. A graph of "The current read on the ammeter" versus "the voltage read on the voltmeter". The current was plotted on the 'y' axis while the voltage was plotted on the 'x' axis. Based on theory, the slope of the line for the graph drawn is equal to the resistance of the fixed resistor in the circuit. The value was determined and a conclusion to the experiment was written. |
