Keep a spent tubelight in a dark place. Rub it vigorously with a thin polythene bag.
It acquires a small electric charge. The electrical charges generated by this simple method of rubbing is static. They are immobile by nature. When charges move, they normally constitute an electric current. It is similarly observed when a plastic comb is rubbed with dry hair. Such objects are called charged objects.
