PW: study of charging a capacitor at constant-voltage

When the capacitor is charging, the voltage at its terminals increases more or less rapidly to reach the value of the voltage imposed by the constant-voltage generator. The model for demonstrating the charge of a capacitor at constant-voltage facilitates the study of the RC dipole. A synchronisation signal can trigger the datalogging system in order to display the beginning of the capacitor's charge. For greater convenience, the capacitor may be discharged immediately using the button located on the rear side of the casing.
