To investigate the variation of current ( I ) with pd ( V ) for copper sulfate solution with copper electrodes.

When a voltage source is connected to a voltameter containing copper electrodes in a copper sulfate solution a current flows through the solution. In this experiment we investigate how the current flowing through the solution varies with different voltages applied across it.

  1. Note that current is 0 when voltage is 0. Record voltage and current values in a table.

  2. Click on the slider to increase the voltage from the potentiometer.

  3. Record the voltage and current readings from the voltmeter and ammeter.

  4. Repeat steps 2 and 3 until you have at least six sets of readings.
