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. 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. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.

So basically an isnstrument that measures charge quantitatively is called an electrometer. An electroscope is a scientific instrument used to detect and measure electricity to reveal the ionization of air by radioactivity and works by testing for the presence of charges.

*It is used to determine the kind of charge on a body.
*It can also be used to find out whether a substance is a conductor,or an insulator.

What is a eletroscope?
An electroscope is an early scientific instrument. It is used to detect and measure electricity or an electric charge on a body.
Which instrument can measure static electricity having a potential difference as low as 0.1 volts?
electroscope
What do you need for a homemade electroscope?
You can find instructions for making an electroscope in several books. The novel "Pulling Through" by Dean Ing contains an appendix that tells you how to make an electroscope (identical to the one the characters in his story used to measure radioactivity levels from nuclear fallout). I built one of these but found it very tricky (it is very difficult to avoid contamination that allows charge to leak from the plates and this will be true of any homemade electroscope).

What are the types of electroscopes?
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope
Principle of electroscope and types of electroscope?
Like charges repel and unlike charges attract each other this is the fundamental principle used in an electroscope to detect presence and amount of charge. There are mainly 2 tpes of electroscopes pith ball electroscope and gold leaf electroscope
If you grounded the electroscope what does that do to the leaves of your electroscope?
...Guys...This is the answer of question...it simple! If we grounded the electroscope..whatever the charge on leaves are, positive or negative (as it depends with which charge you electrolyse the electroscope), if its positive and ground is negative (attraction) or if same + + so repultion
If the leaves of an electroscope spread apart it indicates that?
It indicates that the leaves of the electroscope have received a charge.
Can you give me a sentence for the word electroscope?
An electroscope is an instrument for detecting the presence of static electricity.

negative
