Final answer:
It is true that capacitors smaller than 0.01 µF are often rated in picofarads because the picofarad unit is suitable for describing such small capacitances in electronics.
Step-by-step explanation:
The statement that capacitors smaller than 0.01 microfarads are rated in picofarads is true. Capacitance values can vary widely, and the scale of capacitance is quite broad, encompassing values from picofarads (1 pF = 10-12 F) to millifarads (1 mF = 10-3 F), through microfarads (1 µF = 10-6 F). When dealing with capacitors on the smaller scale of this spectrum, especially those below the microfarad range, it is common to use the picofarad measurement due to convenience and tradition in electrical engineering and electronics.
