A metal rod held in hand and rubbed with wool will not show any sign of of being charged. However, if a metal rod with a wooden or plastic handle is rubbed without touching its metal part, it shows signs of charging. Why??
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.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.Hi. Charge leaves through your hand to Earth. Wood or plastic is insulator, hands are conductor.
