It is not possible to make a ordinary conductor hold it's charge permanently.But you can make a ordinary conductor(e.g.,)a wire to hold charge for a short period.This is because a charge stored in a conductor leaks to the surroundings due to ionisation of air.
But it is possible to charge a conductor like a copper sphere. for this the copper sphere is first connected to ground and a negatively charged ebonite rod near it.the copper sphere becomes positive as the negative charges in it flow to the ground.the sphere is disconnected from ground and the ebonite rod is taken away.now the copper sphere holds positive charge.
note:
it is easy to charge an ebonite rod by rubbing it with fur.

Is ebonite a conductor?
Ebonite is a poor conductor of electricity, it is an insulator. Electrons cannot move easily within it, but can it form and hold a static charge.
What is the charge density for a conductor?
The charge density inside a conductor is always zero
The ability of a conductor to take on a charge is called its?
The ability of a conductor to take on charge is called its conductance.
What is electrical friction the science term?
Energy made avalible by the flow of electric charge through a conductor.
Which metal serves the best conductor of electric charge?
the metal that serves as the best conductor of electric charge is the METAL
When an electric charge moves through a conductor there is an electric in the conductor?
current
Electrical energy is the energy of what?
Electrical energy is the energy made available by the flow of electric charge through a conductor.
Why copper rod cannot be charged?
Because Copper is a conductor and conductors do not hold electricity. The charge flows out. But, A copper rod can be charged if it is in a rubber handle. This will result in the charge staying in the rod, thus charging it.
What is the property of a conductor that opposes the flow of charge passing through it is called?
property of a conductor that opposes the flow of charge passing through it
Where does the excess charge on a copper rod flow to if you don't use an insulator?
If you connect the rod with a conductor, part of the charge will flow to the conductor.
Give examples of static electricity caused by friction?
Energy made avalible by the flow of electric charge through a conductor.
Why is it difficult to charge a metallic conductor which is held with the hands why is it easy charged a non conductor although it is held by the hands?
