Sonam Sharma 7 years, 11 months ago

After the breakdown voltage Vz, a large change in the current can be produced by almost insignificant change in the reverse bias voltage or in other words the zener voltage remains constant even thought current through the zener diode varies over a wide range, this property is used for regulating supply voltages so that they are constant.

What is an electric dipole

Posted by Dushyant Kaushik 7 years, 11 months ago

Kritika Trehan 7 years, 11 months ago

An electric dipole is two charged objects, with equal but opposite electric charges, that are separated by a distance. The electric field caused by a dipole falls off as the cube (third power) of the distance from the dipole, and has a directional variation that depends on whether you’re moving along the line separating the two charges or perpendicular to it. A dipole can be created, for example, when you place a neutral atom in an electric field, because the positively-charged constituents of the atom will be pulled one way, and the negatively-charged constituents the other way, creating a separation of charge in the direction of the field.
