What Are Electric Parts
Electric parts are components that make up an electrical system, circuit, or device. They include but are not limited to:
- Switches: A switch is an electrical component used to turn a circuit on or off. Quick View Switch Types
- Resistors: A resistor is an electrical component that resists the flow of current in a circuit.
- Capacitors: A capacitor is an electrical component that stores energy and releases it when needed.
- Diodes: A diode is an electrical component that allows current to flow in one direction only.
- Transistors: A transistor is an electrical component that can amplify or switch electronic signals.
- Transformers: A transformer is an electrical component that changes the voltage of an alternating current (AC) signal.
- Relays: A relay is an electrical component that switches a high-voltage or current circuit with a low-voltage or current circuit.
- Circuit breakers: A circuit breaker is an electrical component that automatically stops the flow of electricity if it exceeds a certain level.
- Fuses: A fuse is an electrical component that protects a circuit from overloading by melting when the current flow exceeds a certain level.
- Connectors: A connector is an electrical component used to join two or more wires together to complete a circuit.
Electric Parts History
The history of electric parts dates back to the 18th century when scientists and inventors began experimenting with electricity. In 1745, Benjamin Franklin first coined the term “battery” to describe a series of Leyden jars linked together. Later in the 19th century, Michael Faraday discovered the principles of electromagnetic induction, which led to the development of the transformer.
In the late 1800s, the invention of the incandescent light bulb by Thomas Edison sparked the need for electrical components such as switches, sockets, and wiring. The first electric motor was also invented during this time period by Nikola Tesla.
During the early 20th century, electronics began to emerge as a new field of study. Scientists such as Guglielmo Marconi and Lee De Forest made important discoveries in radio technology, which led to the development of vacuum tubes as electronic components. These were used in early radios and amplifiers.
In the mid-20th century, the invention of the transistor by William Shockley, John Bardeen, and Walter Brattain led to a revolution in electronics. Transistors replaced vacuum tubes and became the building blocks of modern electronics.
Today, electric parts continue to evolve with advances in technology, leading to the creation of new components such as microprocessors, integrated circuits, and sensors.
