FAQs
What is a lab electroscope and how does it work?
A lab electroscope is a scientific instrument used to detect electric charge. It typically consists of a metal rod with a bulb at the top, where the bulb contains lightweight leaves of metal or a thin conductive material. When an electrically charged object is brought close to the electroscope, it causes the leaves to either spread apart or come together based on the type of charge present. This movement indicates the presence and nature of the charge.
The basic working principle of an electroscope relies on electrostatic induction. When a charged object approaches, the electrons in the electroscope are either attracted or repelled, leading to a redistribution of charges on the electroscope’s metal components. Thus, the more the leaves diverge, the greater the charge applied to the electroscope, making it a simple yet effective tool for studying static electricity.
What are Van de Graaff generators and their main applications?
Van de Graaff generators are electrostatic machines that generate high voltage direct current (DC). They consist of a moving belt that transfers charge to a metal sphere, building up a substantial electric charge.
