The experiment provides insight into one example of storing renewable energies. If capacitors have been introduced in prior lessons, the Gold Cap also shows the development of electronic components and depicts a further use of capacitors.

One item deals with „Technical application and vocational orientation“.

Information and ideas:
• Do not short-circuit the Gold Cap capacitor. Take care that the alligator clips do not touch when connecting them to the Gold Cap capacitor. Connect the positive pole only to the positive pole, and the negative pole to the negative pole. If you are not sure pole of your wind turbine is positive, test the polarity with a digital multimeter.
• The Gold Cap is a double-layer capacitor consisting of two layers of activated carbon which are separated by an organic electrolyte.
