Charging by Induction
Properties of electric charge
When a charged object is touched to another object, the other object also gets charged with same polarity due to charge transfer. This is called charge by contact.
Charging by Induction
When a charged object is brought closer to another object( not touched), the original object doesn’ t lose any charge and the other object gets charged as well with opposite polarity. The other extreme end of the newly charged object develops polarity same as that of the charged object. This type of charging is called charge by induction.
Properties of electric charge
Electric charge for a body is considered as Point charges if their size is very small in comparison to the distance between them. So the charge is considered to be concentrated at one point. Following are the properties of electric charge in terms of point charges:
