elementary idea and transferring charge

Elementary Idea of Electron Microscope - In optical microscope, the ray of light can be bent by a lens system. By placing the object and the lens system in such a way, we control the direction of the ray to get a magnified image of the object. Since as 'electron' carriers c..

Charging by Friction - Keeping in mind the structure of the atom, we can easily explain charging by rubbing. When glass rod is rubbed with silk, some of the electrons from the atoms on glass are transferred to silk. Because there is a deficiency of electrons in the gla..

Keeping in mind the structure of the atom, we can easily explain charging by rubbing. When glass rod is rubbed with silk, some of the electrons from the atoms on glass are transferred to silk. Because there is a deficiency of electrons in the glass, it becomes positively h..

While charging a capacitor, a battery transfers positive charge from negative to the positive plate. So some work is done in transferring this charge, which is stored in the capacitor in the form of electrostatic energ..

Electrovalent bond is the attractive force between the oppositely charged ions, which comes into existence by the transference of electron..

Electric current is a means by which electrical energy is transferred from one place to another for utilisation. Charges in motion constitute an electric curren..

It is clear that usually the negative charge is transferred when two bodies are rubbed together. The electrons that are less tightly bound tend to move from its atom to the other. The number of electrons that are transferred will be insignificant compared to the total..

We observe various chemical processes in our daily life. It is a common observation that the rates of these chemical reactions vary and depend on certain factors. The knowledge of the rate of a reaction is of importance in industries to ensure optimum productivity. An industrial process needs to be..

It is based on the following principles: 1) Action of sharp points: Charges are leaked from pointed ends of charged conductors. This creates an electric wind (as moving air is ionized) which moves away from the conductor. 2) The property that the charge given to a hol..
