Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFCONCEPT:
- Capacitance is defined as the ability to store charge in a conductor.
q ∝ V
q = C × V
Where q = charge on the conductor; V = Voltage; C = capacitance
- SI unit is the farad (F)
- The capacitance of a parallel plate capacitor
C = (ϵ × A)/d
where d = distance between parallel plate; A = area of parallel plate; ϵ = electric permittivity
EXPLANATION:
C ∝ q
C ∝ 1/V
C ∝ A
C ∝ ϵ
C ∝ 1/d
Hence option 2 is correct.
Additional Information
- The capacitor in series: Two or more capacitors are connected in series if they contain the same quantity of charge.
1/CS = 1/C1 +1/C2
- The capacitor in parallel: Two or more capacitors are connected in parallel if they contain the same voltage.
CP = C1 + C2
