Suppose a charge `+Q_1` is given to the positive plates and a charge `-Q_2` to the negative plate of a capacitor. What is the "charge on the capacitor"?

By increasing the charge on the plate of capacitor .......... .

Derive expression for the capacitance of the parallel plate capacitor,

How much positive and negative charge is there in a cup of water

How much positive and negative charge is there in a cup of water ?

A network of four 10 µF capacitors is connected to a 500 V supply, as shown in Fig. 2.29. Determine (a) the equivalent capacitance of the network and (b) the charge on each capacitor. (Note, the charge on a capacitor is the charge on the plate with higher potential, equal and opposite to the charge on the plate with lower potential.)

If an isolated infinite plate contains a charge Q_1 on one of its surfaces and a charge Q_2 on its other surface, then prove that electric field intensity at a point in front of the plate will be Q//2Aepsilon_0 , where Q = Q_1+Q_2
