Experiment 1 - The Capacitor in a Circuit

Consider the circuit shown. You recognize the electric circuit. If you press down the push button switch and thus close the circuit, nothing visible happens. You did not expect anything else.

Circuit with capacitor. ( Enlarge)

Circuit diagram of a circuit with capacitor.

In fact, you have charged the capacitor. However, you can not observe it. The choice of the capacitor with a capacity of 47 nF was purely arbitrary. Each ceramic capacitor gives you the same result.

In next step you will watch the process of charging more accurately.
