Steven Gatesman Investigating Resistance Plan: The aim of my experiment is to find out how the length of wire will affect the resistance in a circuit. The only item I will change is the length of the wire. Other items such as power pack, the ammeter, the voltage meter and other wires in the circuit will stay the same to ensure that the experiment is a 'fair test'. Using the ammeter reading and the voltage meter reading I can calculate the resistance of the wire by means of Ohms Law. Ohms Law: V=I/R, R=I/V, I=VxR V = voltage I = current R = resistance Using this triangle I can produce the following formula: R = V / I Resistance = voltage / current I will record the results three times so that the final result is reliable. I will start my recordings at 10cm's and then add 5cm's each time. Safety: To ensure that the experiment will be safe I will place the...
