CT: Therefore, electricity is widely used in industries, establishments and in homes. Let us learn how the electricity we use at home comes from the electric power station. There are hydroelectric power stations (energy from water is converted into electricity), thermal power stations (energy from coal is converted into electricity) and nuclear power stations (nuclear energy is converted into electricity). Normally the electric power stations are established at places that are very far from cities and town. Electric power is generated at 11,000 volts (11 kV) with an alternating frequency of 50 Hz.

N: 1. electric (adj): 1640s, first used in English by physician Sir Thomas Browne (1605-1682), apparently coined as Modern Latin electricus (literally “resembling amber”) by English physicist William Gilbert (1540-1603) in treatise “De Magnete” (1600), from Latin electrum “amber,” from Greek elektron “amber” (Homer, Hesiod, Herodotus), also “pale gold” (a compound of 1 part silver to 4 of gold); which is of unknown origin. Originally the word described substances which, like amber, attract other substances when rubbed. Meaning “charged with electricity” is from 1670s; the physical force so called because it first was generated by rubbing amber. In many modern instances, the word is short for electrical. Figurative sense is attested by 1793.
power (n): c.1300, “ability; ability to act or do; strength, vigor, might,” especially in battle; “efficacy; control, mastery, lordship, dominion; legal power or authority; authorization; military force, an army,” from Anglo-French pouair, Old French povoir, noun use of the infinitive, “to be able,” earlier podir (9c.), from Vulgar Latin *potere, from Latin potis “powerful”. Sense of “electrical supply” is from 1896.
station (n): late 13c., “place which one normally occupies,” from Old French stacion, estacion “site, location; station of the Cross; stop, standstill,” from Latin stationem (nominative statio) “a standing, standing firm; a post, job, position; military post; a watch, guard, sentinel; anchorage, port” (related to stare “to stand”), from PIE ste-ti-, suffixed form of root sta- “to stand”.
2. An electric power station is a factory in which energy is converted from one form or another into electrical energy.
