Why must the sphere rod and leaves of a electroscope be a conductor and not an insulator?
A conductor allows charges to move freely throughout its material, which is essential for an electroscope to detect and respond to changes in charge. An insulator would prevent charges from moving between the leaves and sphere rod, limiting the electroscope's ability to function accurately.
How would you ue an electroscope tofindout whether an object is charged or no?
To use an electroscope to determine if an object is charged, first discharge the electroscope by grounding it. Next, bring the object close to the electroscope without touching it. If the leaves of the electroscope diverge, it indicates that the object is charged.
What can an electroscope determine?
An electroscope can determine the presence of electric charges. When a charged object is brought close to the electroscope, it causes the leaves of the electroscope to either repel or attract each other, indicating the presence and type of charge.
What happens when we touch a charged electroscope with our fingers?
When we touch a charged electroscope with our fingers, the excess charge on the electroscope is neutralized by our body, causing the electroscope to discharge and lose its charge. As a result, the leaves of the electroscope will collapse back together.
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.

What would change about the way an electroscope worked if its metal knob was replaced with a plastic one?
Replacing the metal knob of an electroscope with a plastic one would not significantly affect its functionality. The electroscope works by detecting the presence of electric charge on the metal knob, and plastic material does not conduct electricity. The only difference may be that plastic is an insulator and cannot hold a charge like metal, so the electroscope may not be as sensitive in detecting the presence of electric charge.

What would you use to see if something is charged?
an Electroscope

An example of a insulator?
An insulator has several different meanings. The two most common are an electrical insulator and a thermal insulator. an electrical insulator would be polyethylene. a thermal insulator would be wool.
Predict what would happen if you touched the knob of a positively charged electroscope with a negatively charged object?
If you touch the knob of a positively charged electroscope with a negatively charged object, the excess electrons from the negatively charged object will flow to the electroscope, neutralizing the positive charge. The electroscope will become neutral or slightly negatively charged as a result.
What would you use to see if somthing is charged?
You can use an electroscope to see if something is charged. When a charged object is brought near the electroscope, the leaves of the electroscope will either repel or attract each other, indicating the presence of a charge.
What would happen if you touched a positive electroscope with a positive rod?
The leaves of electroscope will diverge a little more because more positive charges will flow from a positive rod
What would make a good insulator?
A nonmetal would make a good insulator.
