An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. [1] There are many different types, ranging from historical handmade mechanical instruments to high-precision electronic devices.
An electroscope can only give a rough indication of the quantity of charge; an instrument that measures electric charge quantitatively is called an electrometer. The electroscope was the first electrical measuring instrument.
The discharge repetition frequency is the measured variable which is a function of the background electrostatic field. Beside static charge control in electrostatic discharge (ESD) sensitive environments, another possible application is the measurement of the atmospheric electric field, if sufficient sensitivity is available.

The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving concepts from electrostatics, atmospheric physics, meteorology and Earth science. [2]
The electric field of the charge C will cause the charges in the volume of the metal to separate, creating regions of induced charge on the inside and outside surfaces of the shell. Now imagine a closed surface S inside the metal of the shell, between the inside and outside surfaces.
Considerations related to electric charge dominate electricity and electronics. Electrical charges interact via a field. That field is called electric field.If the charge doesn't move. If the charge moves, thus realizing an electric current, especially in an electrically neutral conductor, that field is called magnetic.
You recycle your plastic iced tea bottles. Of course you carry a reusable bottle for water. You compost the scraps from your locally sourced, organically grown vegetables. You hardly ever eat red meat. You carpool to work in your electric car. You bike on the weekends.
Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms ...
