This is a type of display that uses tiny polarized crystals that align when current is passed through them. Used in conjunction with a polarized lens they darken when energized. They are very popular in watches, calculators, and laptops.

• LED

• Quartz Crystal

• CRT

• LCD

This is a special type of diode that lights up when a small voltage is applied. They are usually used as indicators or in numerical or alphanumerical displays.

• Zener Diode

• Incandescent Lamp

• LCD

• LED

This consists of an electromagnet, which is used to open or close a contact(s). It is used in switching that requires isolation or high power.

• Rheostat

• Relay

• Transistor

• Inductor

This can consist of a simple wire wound into a helix. It develops a magnetic field when current passes through it. It is also used in tuning circuits and filters. This one passes DC and blocks AC.

• Capacitor

• Inductor

• Transistor

• Semiconductor

A number 12 AWG copper conductor can be placed and safely protected on a 20 amp circuit breaker. What does AWG mean?

• Anode Working Group

• Athermal Wavelength Grating

• American Wire Gauge
