In association with The Solar Spark at the University of Edinburgh

Complete a circuit by placing your hands on two metal plate electrodes.

A solar cell has two electrodes. These have to be connected up to make a circle which we call an electrical circuit.

One side is connected using wires and the other side is connected up with something called an electrolyte.

When you put your hands on the metal plate electrodes, you become the electrolyte. The current can flow through your sweat and your body fluids so a reading is seen on the meter.
