solar cell illumination – for measurement you can choose one of four levels of exposure solar cell
solar cell load – for adjusting the electric current drawn from the solar cell serves rheostat, which can be controlled by this slider
experimental data – there are shown the measured values of voltage and current that can be stored in the table
table of exp. data – a table of experimental values (electric current, voltage) that can be further worked with
table data processing – the data in the table can be displayed in a graph, saved to a computer for further processing, or the table can be deleted and measured again
