Hint: An electroscope consists of a vertical metal rod that sticks out of a glass enclosure; a piece of plastic prevents electric charge from going from the metal rod and metal leaves at the bottom on to the cylindrical enclosure, which is usually metal as well.
Complete answer:
Gold leaf electroscope- A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate. The whole of this part of the electroscope is insulated from the body of the instrument by contact - a charged rod is touched on the surface of the disc and some of the charge is transferred to the electroscope. The electroscope is an instrument for checking a body whether it is electrically charged or not and also used for finding the nature of charge. The gold leaf electroscope is one of the most popular electroscopes. A gold leaf electroscope is the device used to detect electrical charge and, if compared to a known charge, can also detect its polarity. It shows the presence and magnitude of a charge by applying a charge to a top plate of copper connected to two pieces of gold leaf through a stem.
So, the most common type of electroscope is gold leaf electroscope.
Note: An electroscope is a scientific instrument that is used to detect the presence and magnitude of electric charge on a body. There are three classical types of electroscopes: pith-ball electroscope (first), gold-leaf electroscope (second), and needle electroscope (third).
