272-11-4 Understanding Electrical Circuits

Provides a path for the current flow from the power source to the load and from the load back to the power source.

A conductor

Is a simple line design used to represent a component or device in a schematic circuit diagram.

A symbol

Flow is continuous electron flow in the same direction.

Direct current

Is often the result of the failure of a small part within a larger circuit

Excessive current flow

When the circuit operates properly and no damage occurs to the circuit components.

Normal current flow results

Is the part of the electrical circuit that uses the electrical energy provided by the power source to carry out some desired function.

The load

Silver.

The metal that has the greatest conductance is

Is the part of an electrical circuit that provides a difference of potential.

The power source

A power source, a load, and the connecting conductors.

What are the three basic elements of an electrical circuit?

A block diagram is a simplified outline of an electrical system that shows circuits or parts as rectangles and other shapes.

Which of the following is a correct definition for a type of circuit graphic?
