Which is equal to one kilovolt?

One kilovolt is equivalent to one thousand volts. The prefix "kilo-" in the metric system denotes a factor of one thousand. Therefore, when referring to voltage, one kilovolt (kV) is simply a way to express a voltage level that is 1,000 volts. This understanding is essential in various electrical engineering applications and in amateur radio, where voltages can be expressed in kilovolts for convenience, especially when dealing with high voltage systems.

In contrast, other options misrepresent the value associated with one kilovolt. The notion of one one-thousandth of a volt represents a millivolt, which is much smaller in scale. One hundred volts represents a much lower voltage that is not equivalent to kilovolts. Lastly, one million volts translates to one megavolt, which is again a significantly larger measurement. Understanding these prefixes and their corresponding values is fundamental in grasping concepts in electricity and electronics.
