What does one picofarad equate to?

• A. One hundredth of a farad
• B. One millionth of a farad
• C. One trillionth of a farad
• D. One thousandth of a farad

Answer: (C)

One picofarad is defined as one trillionth of a farad. The prefix "pico-" denotes a factor of 10 to the minus 12, which means that one picofarad is equal to \(10^{-12}\) farads. This measurement is extremely small and is commonly used in electronic applications, especially in capacitors, where capacitance can be in the picofarad range. Understanding these metric prefixes is essential in electronics, as they help communicate the scale of components effectively. Other choices, like one millionth or one hundredth of a farad, represent different prefixes such as microfarads and centifarads, respectively, which do not correspond to the definition of picofarads.
