Passive Components are electronic components that do not require a Source of Energy to perform their intended functions. The followings are the examples of Passive Components:
Resistors | |
They resist the flow of electric current. The resistance is measured in Ohms (Ω). R=V/I, where: R=Resistance, V=Voltage and I=Current. | |
Potentiometer | |
It is a resistor with a tap or contact which can be moved to change the resistance. | |
Capacitors | |
Capacitors store energy in its electric field. The capacitance is measured in Farads (F). C=Q/V, where: C=Capacitance, Q=Charge and V=Voltage. Capacitors stop direct current flow (DC). They are an open circuit to DC. | |
Variable Capacitors | |
The capacitance of these capacitors can be changed to adjust a circuit. | |
Inductors | |
Inductors store energy in its magnetic field. They are measured in Henrys (H). L=N,, where: L= Inductance, N=Numbers of Turns, and is the change in Flux linking a coil due to a change in Current through the coil. | |
Connectors | |
These connect one part of an electric circuit with another. Connectors are designed for different power levels and signal types. | |
Switches | |
Switches can be on-off controls (single throw) or change the connection from one circuit to another (double throw). Complex switches can control many circuits at the same time. | |
Relays | |
A relay is a switch that is turned on and off by an electromagnet, or a solid state switch controlled by an optical coupler. |
