Circuits Experiment Aim To see prove the equation Resistance (?) = Potential Difference ÷ Current. This is to be done by setting up a series of circuits containing a voltmeter, an ammeter, cells for the different potential differences, and light bulbs for causing the resistance. Hypothesis I predict that as I increase the amount of bulbs in the circuit the resistance will increase, this is because the electricity must flow through a small filament which has a high resistance already; bulbs have high resistance filaments because they give off more light. I also think that when I increase the number of cells in the circuit, the potential difference will also increase; this is because the cells each have a potential difference on 1.5 volts. Apparatus * 3 Power Cells * Voltmeter * Ammeter * Power leads * Bulbs with a known resistance Method 1. Set-up a circuit in accordance to the diagram below 2. Record the amps and potential difference values in a...
