Electrical Definitions For Dummies

Alternating current ac an electric current that reverses its direction many times a second at regular intervals.

Electrical definitions for dummies. Actuator solenoid the solenoid in the actuator housing on the back of the injection pump which moves the control rack as commanded by the engine controller. Here is a brief overview of the functions of each of these basic electronic components. A glossary of electrical terms become an electrician electricians are skilled tradespeople working in a variety of different residential and industrial settings. The text book definition of an electrical circuit goes something like this.

What is the voltage across an electrical circuit with a current of 10a and 200ω of resistance. The third piece of the puzzle is called power abbreviated p in equations. The energy in a single lightning bolt is enough to light 100 powerful lamps for a whole day or to make about twenty thousand slices of toast. V i x r.

This site aims to provide all the i. The three key concepts you need to know before working with electronic circuits are current voltage and power. As you progress in the electrical trade you ll hear a bunch of electrical terms being tossed around like their common knowledge. You will work with a number of basic electronic components when building electronic circuits including resistors capacitors diodes transistors and integrated circuits.

I f you ve ever sat watching a thunderstorm with mighty lightning bolts darting down from the sky you ll have some idea of the power of electricity a bolt of lightning is a sudden massive surge of electricity between the sky and the ground beneath. But i know that this will not help you understand much as it is quite vague. It takes years to get a firm understanding of what they all mean. Below you ll find over xx definitions of electrical terms.

Current flow direction it is not known for sure what direction currents flows. It s one of the most basic. The conventional theory of current flow is from positive to negative. Alternator a device which converts mechanical energy into electrical energy.

Current is the organized flow of electric charges through a conductor and voltage is the driving force that pushes electric charges to create current. V 10 x 200. It is an interconnection of electrical elements used to transmit power. Ampacity the maximum amount of electric current a conductor or device can carry before sustaining immediate or.

Alternating current ac a flow of electrons which reverses its direction of flow at regular intervals in a conductor. Dedicated circuit a circuit that has only one receptacle and is used for one load that has a high current rating. The current in an electrical circuit with a voltage of 120v and 12ω of resistance is 10a. Resistors a resistor is a component that resists the flow of current.

The current in an electrical system with 10a and 200ω of resistance is 2000v. Electric circuit explained. Ammeter an instrument for measuring the flow of electrical current in amperes ammeters are always connected in series with the circuit to be tested.
