If a large enough electric field is applied, even an insulator will conduct an electric current, as is evident in lightning discharges through the air. Explain how this happens, taking into account the opposite charges in an atom and how ionization occurs.
Step 1 of 3
Solution 37E If we apply the potential difference in the two sides of an insulator, the potential difference creates an electric field inside the insulator. This electric field applies force to the electrons of in the atoms of the medium. Now if the electric field is high enough, the force due to electric field will be higher than the binding force of the electron to the toms, that is the force by which the nucleus attracts the electron. And if the force is higher than the binding force of electron the electron will come out of the atoms and will starts moving according to the direction of the field. This will create current and we will see that electric discharge through the insulator.
