Electrical Light Wiring Diagram
Bell A transducer which converts electrical energy to sound.
Motor A transducer which converts electrical energy to kinetic energy (motion).
AC supply AC power supply symbol Supplies electrical energy. AC = Alternating Current, continually changing direction.
Circuit diagrams show the connections as clearly as possible with all wires drawn neatly as straight lines. The actual layout of the components is usually quite different from the circuit diagram and this can be confusing for the beginner. The secret is to concentrate on the connections, not the actual positions of components.
