About knowledge of electrostatic a few physics

From;    Author:Stand originally
1.What does the main parameter with electrostatic object have?
What is its unit?
A. Charge volume
More or less to express what state electrostatic charge is measured with n Q, its unit is coulomb C, because the unit of coulomb is too big,use small library or accept warehouse normally
1 coulomb = 1000000 small libraries
Surveying powdery system electrified reach its to carry on his shoulder or back to be compared character, measure antistatic its should be measured when the function that serve electrified charge volume.
B. Electrostatic voltage
It is easier that because be in,very much circumstance measures electrostatic potential, another commonly used electrostatic parameter is electrostatic potential, its unit is volt, but as a result of electrostatic voltage normally very tall, because this is commonly used a bigger unit - kilovolt (KV)
The commonly used method when the electrostatic voltage that measures an object is to use blame contact electrostatic volmeter, when be being measured, do not contact with the object that be measured, to be being measured consequently the static film of the object rings very small, commonly used appearance has EST101 explosion proof electrostatic volmeter,
2.What to measure electrostatic main instrument equipment to have?
The instrument that measures electrostatic charge volume has charge to measure a watch, measure electrostatic potential to be able to use electrostatic volmeter. Measure material to have a lot of measurement characteristicly if electrostatic appearance is tall list of volume of block plan, charge.
3.What does the parameter of the electrostatic performance that measures material have?
Measuring the how much commonly used parameter with electrified object is electrostatic charge volume and electrostatic voltage, measure nevertheless plastic, balata, antistatic floor (face) , of the material such as carpet antistatic function moment, use resistor normally, resistor rate, bulk resistor rate, exterior resistor rate, charge (or voltage) half-life, electrostatic capacitance, dielectric constant, among them the the most commonly used, most reliable is resistor and resistor rate.
