What is one farad capable of holding under a pressure of one volt?

• A. One electron
• B. One coulomb
• C. One watt
• D. One ampere

Answer: (B)

One farad is defined as the unit of capacitance that can hold one coulomb of electric charge under a potential difference of one volt. This definition arises from the fundamental relationship between charge (Q), capacitance (C), and voltage (V), encapsulated in the formula \( Q = C \times V \). When the capacitance is one farad and the voltage applied is one volt, the amount of charge stored is exactly one coulomb. This means that a capacitor with a capacitance of one farad can store a charge of one coulomb when a voltage of one volt is applied across its terminals. Understanding this principle is critical for anyone working in aircraft electronics, where capacitors are used in various applications including energy storage, filtering, and signal coupling.
