Circuit Diagrams & Symbols
You probably already know that electrical engineers do not draw pictorial diagrams for every circuit. Instead, they draw symbolic diagrams that represent a physical situation.

Lessons In Electric Circuits
A convenient source of AC voltage is household wall-socket power, which presents significant shock hazard. In order to minimize this hazard while taking advantage of the convenience of this source of AC, a small power supply will be the first project, consisting of a transformer that steps the hazardous voltage.

GCSE Physics: Circuit Symbols
ammeter, battery of two cells, battery of three cells, diode, fuse, lamp, light dependent resistor (ldr), switch (closed), switch (open), thermistor, variable resistor, voltmeter.

Circuit Symbols of Electronic Components
Circuit symbols are used in circuit diagrams which show how a circuit is connected together. The actual layout of the components is usually quite different from the circuit diagram.

Circuit Schematic Symbols
The schematics symbols for most major electrical components can be found in this table. However, each component may have numerous possible representations. In cases where there is more than one common symbol we have tried to give an alternate representation.

Electric Circuits
In the previous unit we looked at voltage, current, and resistance individually. Now it's time to put them all together and look at the concept of an electric circuit.

Circuits for the Hobbyist
Active Power Zener, Active Antenna for AM-FM-SW, Active Antenna for HF-VHF-UHF, Active FM Antenna Amplifier, Aviation Band Receiver, Alternating On-Off Switch, Audio Booster with 1 Transistor, Audio Pre-Amplifier, Automatic 9-Volt NiCad Battery Charger, Auto-Fan, automatic temperature control, and more in an alphabetized list.

Drawings and Sketches
As a Construction Electrician you will be required to read and interpret drawings and specifications, sketches, and electrical diagrams. Before you can work with drawings effectively, you must know how to interpret electrical symbols correctly.
