How does an electroscope work to detect static electricity?
Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines.
Principle of electroscope and types of electroscope?
An electroscope is a device used to detect the presence of electric charges. It works on the principle of charge induction, where like charges repel each other causing a leaf or needle to diverge. The two main types of electroscopes are the gold-leaf electroscope, which uses thin gold leaves, and the pith-ball electroscope, which uses lightweight balls of plant material.
What happens when a charged electroscope is connected to an uncharged electroscope by a metal wire?
Charge would flow from the charged electroscope to the initially uncharged one, until the charges are equal on both. At that point, the potential on both ends of the wire would be equal, there would be no voltage across the wire, and no more current would flow. Both electroscopes would then be charged, with charge of the same sign, and with half as much charge as the initially-charged one had.
When the electroscopes foil leaves are charged and there is contact with the charged plastic rod this is an example of Charge by?
This is an example of charge by conduction. When a charged object, like the plastic rod, comes into contact with a neutral object, like the electroscope's foil leaves, the charge is transferred through direct contact, causing the leaves to become charged as well.
What are the kind of electroscope?
There are two main types of electroscopes: gold-leaf electroscope and pith-ball electroscope. Gold-leaf electroscope uses thin gold leaves to detect electric charges, while pith-ball electroscope uses lightweight balls made of pith or other materials that can be attracted or repelled by electric charges.
What are the types of electroscopes?
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope

What does an electroscopic measure?
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force.

Name 3 things gold is used for?
Gold is used for jewelery which is a key use. It is also used by the world of finance and governments to back up currency. Gold is also used in electroscopes by physicists. Hi-Fi enthusiasts also swear that gold plated leads give a better quality sound.

What Can you Observe That Uses Static Electricity?
basically the charges concentrate around sharp points so an "S" shape balanced in the center will rotate .. van degraff generators usually have one of these. electric meters made from gold leaf .. the gold leaves repel against gravity sometimes used as dosimeters since they measure voltage until discharged also called electroscopes. hi voltages can ionize air so you can see hear and smell the ozone
What is the function of an electroscope?
Well it can be used for radiation, etc. the main function is to demonstrate various electrostatic phenomena, e.g., conduction and induction of electric charges. it can also be used to see if something is charged which should make the two fine aluminum blades repel. You can find more information on this site http://www.orau.org/ptp/collection/electroscopes/electroscopeintroduction.htm hope this helped you understand a little more
Why a charged electroscope will discharged when placed near a radioactive material?
1. Electroscopes can be used to detect electronic charges and when a electroscope is given negative charges they repel each other and spread apart. They will remain apart until their electrons have somewhere to go and it combines with positive charges. When nuclear radiation is moving through the air it can remove electrons from some molecules In the air and cause other molecules in the air to gain electrons. - B0N3S
