Mounted Solar Cell
A 1000 mA cell with a voltage output of 0.45V mounted on a wooden base. The solar cell along with the mounted lamp and a 24 or 36W lamp provides a neat set up for the “Output of a solar cell” practical investigation.
Parallel Circuit Board
The board consists of three lamps arranged in parallel. The current in each branch can be measured as well as the total current in the circuit. The voltage across each lamp can also be measured as well as the voltage across the parallel block.
