Electrical short forms pdf

Electrical short forms pdf point where those electrons enter an electrical circuit is called the “source” of electrons. The point where the electrons leave an electrical circuit is called the “return” or “earth ground”. The exit point is called the “return” because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons’ starting point and the point where they return to the source is called an electrical circuit’s “load”.

Converters can change AC to DC and vice versa. Resistance in series circuits is the sum of the resistances. Electrical and electronic circuits can be complicated. Making a drawing of the connections to all the component parts in the circuit’s load makes it easier to understand how circuit components are connected. Drawings for electronic circuits are called “circuit diagrams”. Drawings for electrical circuits are called “wiring diagrams”. Diagrams may also be created digitally using specialized software.

A schematic is a diagram of an electrical circuit. Schematics are graphical representations of the essential connections in a circuit, but they are not life-like depictions of a circuit. Schematics use symbols to represent components in the circuit. Conventions are used in a schematic to represent the way electricity flows.

The common convention we use is from the positive to the negative terminal. The realistic way electricity is from the negative to the positive terminal. The diagrams are a big help when workers try to find out why a circuit does not work correctly. The current flowing in an electrical or electronic circuit can suddenly increase when a component part fails. This can cause serious damage to other components in the circuit, or create a fire hazard. The standard return for electrical and electronic circuits is the earth ground.
