Questions
Four metallic plates, each with a surface area of one side A, are placed at a distance d apart from each other. The two inner plates are connected to point A and the other two plates to another point A as shown in fig. Then the capacitance of the system is
detailed solution
Correct option is B
The two condensers in the middle are connected together .i.e., the connected plates act as a single conductor. In this way, effectively there are two capacitors connected inparallel. The capacity of each capacitor is given byC=ε0AdNet capacitance between A and B is given byCAB=C+C=2ε0A/dSimilar Questions
Two capacitors C1 and C2 having capacitance respectively are connected as shown in the figure. Initially C1 has charge 4 and C2 is uncharged. After long time closing the switch S :
