10 mm × 10 mm क्षेत्रफल वाले एक समानांतर प्लेट संधारित्र (parallel plate condenser) में बेरियम टाइटनेट क्रिस्टल डाला जाता है। 2 mm की दूरी वाली प्लेटें 10-9 F की धारिता (capacitance) देती हैं। यदि ε0 = 8.854 × 10-12 F m-1 है, तो क्रिस्टल का सापेक्ष परावैद्युतांक (relative dielectric constant) लगभग कितना होगा?
