Which is equal to one kilovolt?
The correct answer is C: One thousand volts. One kilovolt equals one thousand volts. The prefix 'kilo-' means one thousand, so 1 kV = 1,000 V.
This is a straightforward unit conversion. Kilovolts (kV) are used for high voltages, while volts (V) are used for lower voltages. For example, power transmission lines might operate at hundreds of kilovolts. Understanding voltage unit conversions is important for safety and for understanding equipment specifications.
Exam Tip
Kilovolt = 1000 volts. Remember: One kilovolt (1 kV) equals one thousand volts (1000 V). Kilo- means thousand.
Memory Aid
"**K**ilovolt = **K**ilo = **T**housand **V**olts (think 'KV = KTV' = Kilo = Thousand Volts)"
Real-World Application
A high-voltage power line operating at 10 kilovolts is actually at 10,000 volts. This is extremely dangerous voltage. In amateur radio, you typically work with much lower voltages (12-13.8 volts for mobile, 120-240 volts for home), but understanding that 1 kV = 1000 V helps you understand high-voltage safety requirements.

Why Other Options Are Wrong
Option A: Incorrect. One one-thousandth of a volt (0.001 V) is one millivolt, not one kilovolt. You have the relationship reversed.
Option B: Incorrect. One hundred volts is 0.1 kilovolts, not 1 kilovolt. 1 kV = 1000 V, not 100 V.
Option D: Incorrect. One million volts is 1000 kilovolts, not 1 kilovolt. You multiplied instead of using the correct conversion.
