Diodes act as one-way valves for electrical current. They allow current to flow easily in one direction but block it in the opposite direction.
Glimmer watched as the Capacitor filled up with water, then gently trickled it out to flatten the uneven surges.

Farads (F), usually measured in microfarads ( F) or picofarads (pF). Ready to Start Designing
These components bridge the gap between electrical signals and physical user interaction or connectivity.
A relay is an electrically operated switch.
They store electrical energy in an electrostatic field. They block direct current (DC) while allowing alternating current (AC) to pass. They smooth out voltage fluctuations in power supplies.
Passive components do not require an external power source to operate. They cannot amplify or increase the energy of an electrical signal. Instead, they attenuate, store, or delay electrical current.
