Which is equal to one microvolt?

• A. One thousandth of a volt
• B. One one-millionth of a volt
• C. One hundredth of a volt
• D. One ten-thousandth of a volt

Answer: (B)

One microvolt is defined as one one-millionth of a volt. The prefix "micro-" in the metric system denotes a factor of 10^-6, or one millionth. This means that if you have one microvolt, you are essentially working with a very small voltage, specifically 0.000001 volts. Understanding this is crucial in various fields, especially in radio communications and electronics, where extremely low voltage measurements can be common. For instance, in ham radio operations, signals can often be quite weak, requiring precise measurement and manipulation of these small voltage levels. The other options represent different factors of voltage that do not correspond to the definition of a microvolt. One thousandth of a volt refers to a millivolt, one hundredth of a volt refers to a centivolt, and one ten-thousandth of a volt refers to a decivolt. All of these have different prefixes and are not equivalent to one microvolt.
