Explain the following, giving proper reason : (a) During charging of a capacitor, displacement current exists in the capacitor. But there is no displacement current when it gets fully charged. (b) The frequency of microwaves in ovens matches with the resonant frequency of water molecules. (c) Infrared waves are also known as heat waves.
In the process of charging of a capacitor, the current produced between the plates of the capacitor is :
What is meant by the term 'displacement current' ? Briefly explain how this current is different from a conduction current.
What is a displacement current ? How is it different from a conduction current ?
A capacitor is charged by a battery. Between the plates, during process of charging :
Figure 8.5 shows a capacitor made of two circular plates each of radius 12 cm, and separated by 5.0 cm. The capacitor is being charged by an external source (not shown in the figure). The charging current is constant and equal to 0.15A.
