CAPACITOR
A capacitor is a device for putting away electrical energy comprising of two conductors in neighboring and protected (insulated) from one another.
NO WORK DONE SINCE NO ELECTRIC FIELD
At first when the capacitor is being charged, no charge on one or the other plate . For this situation, the electric field between the plate is zero.
Let little small charge dq is moved from one plate (right) to another(left) plate. No work is needed since there is no electric field against it.
WORK DONE AGAINST THE ELECTRIC FIELD
Later next gradual charge dq is to be moved from the right plate to left.Work must be done against the electric field.Energy is added each time at whatever point each steady charge dq is moved from right plate to passed on plate.
ENERGY OF CHARGED CAPACITOR MAY BE SAID TO RESIDE IN THE ELECTRIC FIELD BETWEEN THE PLATES.
MORE the VOLTAGE, THE MORE POTENTIAL DIFFERENCE AND HAVE GREATER ELECTRIC FIELD.
ENERGY STORED IN A CAPACITOR
INCREMENTAL TRANSFER OF CHARGE
POTENTIAL DIFFERENCE
WORK DONE IS STORED AS ELECTRICAL POTENTIAL ENERGY
