Luke Wyatt Experiment 101 15/11/06 Experiment 101: Simple measurement of resistance by the ammeter-voltmeter method Risk Assessment The Experiment had a very low risk as it only relies on an electrical circuit. Therefore the only risk in this experiment is as stated below 1. Electrical risk – As the circuit is electrical Experiment Aim The aim of the experiment is to measure the voltage and current in a simple circuit with a given resistance and use the readings for the two to calculate the resistance in the circuit Below is a list of all the apparatus which was used in the experiment Unknown resistance Voltmeter Ammeter Electric cell Rheostat Switch Below is a diagram of how the apparatus was set up in order to collect my results. 1of 6

Luke Wyatt Experiment 101 15/11/06 Theory From ohms law, I V R = Where R is the Resistance, V is the potential difference in volts, and I is the current in amps Also it can be written IR V = Also when a graph is plotted of voltage over current the gradient of the line gives the resistance. Method I have made some slight modifications to the method in the manual. These are outlined below. After each reading the switch will be opened and the rheostat
