Capacitors Guide: Types, Uses and Choosing the Right One
When a capacitor is connected to a voltage source, like a power supply or battery, it causes a voltage difference between the plates, creating an electrical field. How does this happen? Electrons in the conductor connected to the negative terminal of the voltage source are repelled and flow onto one of the conductive plates, giving it a negative charge.
