Converts rough AC-rippled voltage into smooth, clean DC voltage in power supplies.
By combining these resources with our PDF guide, you'll be well on your way to becoming proficient in basic electronics components and their functions.
As a switch, a tiny current at one terminal can turn a much larger current on or off at the other terminals. As an amplifier, it boosts a weak input signal into a much stronger output signal.

Capacitors store electrical energy in an electrostatic field. They are used for filtering (removing noise from power supplies), coupling (allowing AC signals to pass while blocking DC), and timing circuits. Converts rough AC-rippled voltage into smooth, clean DC
A resistor is perhaps the simplest component. Its primary function is to resist the flow of electric current , thus limiting the amount of current that can pass through a part of a circuit. Think of it like a narrowing in a pipe, which restricts the flow of water.
A resistor is the most common passive component found in electronic circuits. Its primary function is to resist or limit the flow of electrical current. ---[===]--- (IEC Symbol) -/\/\/\/\- (US Symbol) Primary Functions

A defining characteristic of an inductor is that it resists changes in current. This makes them essential for applications like filtering out unwanted high-frequency noise in power supplies, tuning circuits in radios, and energy storage in switching power supplies.
