Circuit 218: Generating hydrogen in an environmental friendly way
Setup information
Install the resistor and the jumper as shown in Fig. 2.218. Then install the moving-coil instrument and the
solar cell. We are using two wires with bare ends as electrodes, which we dip in a glass filled with water.
Check the placement on the board again and only then expose the solar cell to strong light.
Components required:
1 x 220 Ω resistor,
1 x solar cell, 1 x moving-
coil instrument,
1 x breadboard
