The SI unit of capacitance is
A{'text': 'joule per volt-squared', 'label': 'A'}
B{'text': 'volt-coulomb', 'label': 'B'}
C{'text': 'farad', 'label': 'C'}
D{'text': 'coulomb', 'label': 'D'}
Answer & Solution
Correct answer: C. {'text': 'farad', 'label': 'C'}
1. Capacitance C = Q / V.
2. Units are coulomb per volt; 1 C/V = 1 farad (F).
3. (D) is dimensionally energy / V², not C.
