Just after posting the question I got the answer. But I didn't knew how to delete the thread which I created. Can you help me with this. By the way thanks for the answer.anuttarasammyak said:Hi. Charge leaves through your hand to Earth. Wood or plastic is insulator, hands are conductor.
Also : Connecting the rod to a body - or Earth will have the effect of vastly increasing the Capacitance and V=Q/C so the Potential change will be minuscule.anuttarasammyak said:Hi. Charge leaves through your hand to Earth. Wood or plastic is insulator, hands are conductor.
Static charge is caused by the transfer of electrons between two objects. When two objects rub against each other, one object can lose electrons and become positively charged, while the other object gains electrons and becomes negatively charged. This imbalance of charge results in static electricity.
When a metal rod is rubbed with wool, electrons from the wool are transferred to the metal rod, creating a negative charge on the rod. This negative charge can then attract positive charges from other objects, creating a static charge.
When objects are rubbed together, friction causes the transfer of electrons between the two objects. This transfer of electrons creates an imbalance of charge, resulting in static electricity.
Static charge can be discharged by touching the charged object to a grounded object. This allows the excess electrons to flow from the charged object to the ground, neutralizing the charge.
In most cases, static charge is not dangerous. However, in certain situations, such as in the presence of flammable gases or liquids, static charge can cause sparks that can lead to fires or explosions. It is important to be aware of potential static charge hazards and take precautions to prevent them.
