Basic Electronic Components and Its Symbol
Fixed Capacitor
A capacitor is a device that consists essentially of two conducting surfaces separated by a dielectric material like air, paper, mica, ceramic, glass, or Mylar. It makes it possible to store electric energy.
Light Emitting Diode (LED)
A diode that will produce light when current flows through it.
Resistor
A resistor is a device with a known value of resistance. Its main function is to reduce voltage and to limit the flow of current in a circuit.
Zener Diode
Allows current flow in one direction, but also can flow in the reverse direction when above breakdown voltage
Diode
Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators.
Variable Resistor
Variable resistors are used when it is necessary to change the amount of resistance in a circuit. There are two common variable resistors, the potentiometer and rheostat.
