A 1 farad capacitor charged with 1 coulomb has potential difference of how many volts?

A 1 farad capacitor charged with 1 coulomb has potential difference of how many volts?

• A. 0
• B. 1
• C. 10
• D. 100

Answer: (B)

Voltage across a capacitor is found from V = Q / C, meaning the stored charge per unit capacitance determines the voltage. With Q = 1 coulomb and C = 1 farad, V = 1 / 1 = 1 volt. So the potential difference is 1 volt.
