Science Coursework. Aim: I want to find out how the length of the wire affects its resistance. Method: 1. Set up the circuit with the... cm wire 2. Switch on the power supply 3. read the voltage across the wire, and the current 4. Change the length of wire x to 40cm, 60cm, 80cm, and 100cm 5. Read the voltage and current 6. Record voltage and current in results table. Factors: The factors are: * The current * Length of wire * Voltage across the wire * Power Supply The factor which I will change will be the length of the wire, because I want to know how the length of the wire changes the resistance. Additionally I will be measuring the wire. The factors that I will be controlling would be the power Supply to find the Current the equation is I=V/R * I= The Current * V= The voltage * R=The resistance The factors I will keep the same are: * The type of metal being...
