Electrophorus machine and capacitor.
Two Crowns • Две короны. Перезалил качество лучше! Caution: High Voltage! It is believed that a capacitor charges only when connected to an electrical circuit. However, opposite charges on the plates also occur when the capacitor is connected to a high-voltage source via only one terminal. Therefore, it can be said that the capacitor is charged because opposite charges appear on the inner surfaces of the plates.
