Which instrument is used to detect the presence of static electric charge?
An electroscope is a very simple instrument that is used to detect the presence and magnitude of electric charge on a body such as static electricity.
What is charge detection?
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.
Which device is used for detecting an electric charge and identifying its polarity?
The Gold-leaf electroscope is a device used for detecting an electric charge and identifying its polarity. It consists of a vertical conducting rod passing through a rubber stopper fitted in the mouth of a glass vessel.
Which is static electrical device?
A transformer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between two windings. It transforms power from one circuit to another without changing its frequency but may be in different voltage level.
What is the name of this device that is used to detect charges?
electroscope, instrument for detecting the presence of an electric charge or of ionizing radiation, usually consisting of a pair of thin gold leaves suspended from an electrical conductor that leads to the outside of an insulating container.
What is the use of gold-leaf electroscope?
A gold-leaf type electroscope is a device used to detect the presence of electric charge on a body and its relative amount.
