... amount of material for the electrons to move through so more can flow through the solution at one time. This is also the same as Resistance being directly proportional to the reciprocal of the surface area of the copper plates and hence to the volume of liquid between them. Equipment Here is a list of equipment which should be set up as in diagram 1: * 1 power supply set at 4 volts * 1 beaker * 2 copper plates * 1 ammeter - 1 to 10 amps * 1 voltmeter - 1 to 20 volts * 1 connection block * 1 measuring cylinder * 1 ruler * 5 wires * 1 thermometer Plan For this experiment, different depths of 0.5M copper sulphate solution were put into a beaker with two copper plates. The plates were a fixed distance apart and the same ones were used throughout the experiment. Therefore, by increasing the depth, the volume increases and the immersed surface area of the ...
