Term of the Moment
ECC
Definition: electricity
An electric charge. Electricity travels at the speed of light (approximately 186,000 miles per second or 300 million meters per second). In a single second, electricity would circle the earth at the equator more than seven times. As it travels in a wire, the speed is slowed a small amount due to the resistance in the metal.
Electricity Is a Weird Phenomenon
Because an electrical current flows in a circuit, it is natural to think of individual electrons flowing. However, it is the electrical field that "flows." In an alternating current, the electrical field oscillates back and forth over a tiny distance 60 times per second in the U.S. (50x in other countries).
Volts, Amps and Watts
Electrical pressure (force) is measured in "volts," and the flow (current) is measured in "amps" (amperes). The amount of work produced is measured in "watts" (amps X volts). See wireless electricity, volt, ampere, watt, nanosecond, electron, electrical and electronic.
