In electrical terms, what does the prefix 'kilo' represent?

The prefix 'kilo' in electrical terms represents one thousand, or 1,000. This is a standard unit of measurement in the International System of Units (SI), where 'kilo' is used to denote a factor of one thousand. For example, in electrical contexts, a kilowatt (kW) equals 1,000 watts, and a kilometer (km) equals 1,000 meters. Understanding this prefix is essential for interpreting measurements and calculations in electrical work, as it often relates to power, energy, and distance.

The other choices represent different magnitudes. For instance, 100 represents a smaller scale, 10,000 indicates a larger factor but not the correct use of 'kilo', and 1,000,000 corresponds to the prefix 'mega', which denotes one million. Each of these prefixes plays a specific role in electrical communication and calculations, but 'kilo' distinctly means 1,000.
