All About Electrical Components
Electrical components are the basic electronic elements that have tow or more connecting leads or metallic pads. The components are connected together by soldering so that they create an electric circuit. Some of the components are packaged singly, such as in resistors and transistors, while others are packaged as integrated circuits, such as a resistor array. The components can be active or passive. Active components have both gain and directionality, while passive components do not have either of these. Electricians call passive components electric elements. An example of an active component would be a semiconductor. In order to make an electrical connection, various components are needed. These include: - Terminal, which is a device for joining electric circuits - Connector, which is used for joining wires. Some examples of connectors are screw terminals, sockets, terminal blocks and headers. - Cords - each appliance has a cord attached with a plug on the end, that fits into an electrical outlet - Switches - components that open and close the circuits by turning them on and off - Resistors - components that dissipate the electrical energy as heat - Protection devices - passive elements that prevent circuits from becoming overloaded - Capacitors - components that store the electrical charge in a field and are used for filtration in the electronic circuits. - Magnetic devices - components that use magnetism - Power sources - battery, fuel cell, etc. - Transducers, sensors and detectors You may not realize that the wiring in your home is made of up very complicated parts, all of which have to work together to give you the electrical power you need.
