संकल्पना:

समांतर प्लेट धारकतेची कॅपेसिटन्स द्वारे दिली जाते:

\(C = \frac{{ϵ A}}{d}\)

जेथे ϵ हा पराविद्युत स्थिरांक आहे. हवेसाठी, ϵ चे मूल्य आहे:

ϵ = 8.854 × 10-14 C2/N-cm2

A हे प्लेट्सच्या काटछेदी क्षेत्रफळ आहे

d हे प्लेट्समधील अंतर आहे

गणना:

d = 0.1 cm, A = 10 cm2, and ϵ = 8.854 × 10-14 C2/N-cmसह, धारकतेचे मूल्य असेल:

\(C = \frac{{8.854× 10^{-14}× 10}}{0.1}\)

C = 8.854 × 10-12 F

C = 8.85 pF
