Electric Charge
Electric Charge
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
o
Electromagnetism is the phenomenon of the interaction of electric currents or fields and magnetic fields. o
o
When insulating surfaces are rubbed against each other, a static charge is developed which gets discharged after getting in contact with a conductor.
Only one of the two charges( or polarity) gets developed on rubbing – either positive or negative. An object becomes positively charged when it loses the loosely bound electrons to another object while rubbing. The other object gains electrons and becomes negatively charged.
o When like charges are brought near, they repel each other. Unlike charges attract each other. o
o
The charges get neutralized when the two bodies are brought in contact.
An example of electric charge generation through rubbing of glass rod with silk and plastic rod with silk is mentioned below:
