a capacitor is charged by connecting it to a DC source (Figure 19-3), electrons are removed from the plate connected to the positive battery terminal and are deposited on the plate connected to the negative terminal. This flow of current continues until a voltage equal to the battery voltage is established across the plates of the capacitor (Figure 19-4).
What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.
Now all manufacturers choose the ones that have positive and negative poles, that is, they are marked with "-" for negative poles. Horn capacitors are easier to distinguish.
