explain the effect of a metal sheet on the capacitance of capacitor when gap is completely filled by metal sheet |
Answer» <html><body><p>ghffgExplanation:Initially (before metal sheet <a href="https://interviewquestions.tuteehub.com/tag/inserted-7275787" style="font-weight:bold;" target="_blank" title="Click to know more about INSERTED">INSERTED</a>) the capacitance of a <a href="https://interviewquestions.tuteehub.com/tag/parallel-1146369" style="font-weight:bold;" target="_blank" title="Click to know more about PARALLEL">PARALLEL</a> plate capacitor is <a href="https://interviewquestions.tuteehub.com/tag/c-7168" style="font-weight:bold;" target="_blank" title="Click to know more about C">C</a>= dAϵ 0 where A be the area of plates and d be the separation between parallel plates.When a metal sheet inserted fully halfway between the parallel plates, the capacitance will be divided into two capacitors C 1 ,C <a href="https://interviewquestions.tuteehub.com/tag/2-283658" style="font-weight:bold;" target="_blank" title="Click to know more about 2">2</a> and they are in series.Thus, C 1 = (d/2)Aϵ 0 =2C and C 2 = (d/2)Aϵ 0 =2CThe equivalent capacitance , C 12 = C 1 +C 2 C 1 C 2 = 2C+2C2C×2C =C</p></body></html> | |
