An electrostatic fieldmeter, also called a static meter is a tool used in the static control industry. It is used for non-contact measurement of electrostatic charge on an object. It measures the force between the induced charges in a sensor and the charge present on the surface of an object.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge . The word "static" is used to differentiate it from current electricity , where an electric charge flows through an electrical conductor .
Electrostatic voltmeter operation Electrostatic voltmeter mechanism Note the curved plates (sectors) toward upper left. The operating principle of an electrostatic voltmeter is similar to that of an electrometer; it is, however, designed to measure high potential differences, typically from a few hundred to many thousands volts.
The electric field, , in units of Newtons per Coulomb or volts per meter, is a vector field that can ... machines that create static electricity.
He referred to static electricity as "electric fire", "electric matter", or "electric fluid". [31] The term "electric fluid" was based on the idea that a jar could be filled and refilled when it became empty. [3] That led to the revolutionary idea of "electrical fire" as a type of motion or current flow rather than a type of explosion. [36]
