The electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage. • Philip M Russell Ltd • Web: http://www.hemelprivatetuition.co.uk
