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??

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.
