|ATX|| Advance Technology Extended|
Up to 12" x 9.6"
Most popular form factor.
|Volt||A measure of electrical "pressure" differential.|
|Amp||A measure of electrical current. The symbol for Amps is A|
|Ohm||A measure of resistance to electricity. Devices are rated according to how much resistance they offer to electrical current.|
|Watt||Watts measure the total electrical power needed to operate a device. Watts are calculated by multiplying volts by the amps.|
|DC||Direct Current . It only travels in one direction.|
|Rectifier||a device that converts AC to DC.|
|Inverter||a device that converts DC to AC|
|Transformer||a device that changes the ratio of voltage to current.|
|Conductors||Material, such as gold or copper, that easily conducts electricity.|
