The sphere, rod, and leaves of an electroscope need to be conductors to allow the flow of electric charge. When they come into contact with a charged object, electrons can move freely within the conductors, causing the leaves to diverge due to electrostatic repulsion. If they were insulators, the charge would not be able to distribute and the electroscope would not function.
What else can I help you with?
Why must a sphere rod and leaves of an electroscope be a conductor?
When a negatively charged rod touches the sphere of the electroscope, negative sharge spreads throughout the metal. Since the leaves are both negatively charged, the free ends repel and move away from each other. When a positvely rod touchs the sphere, negative charges move toward the sphere, causing the leaves to be positively charged. hope this helps :)
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 can gold leaf electroscope be used to detect an electric charge?
In order to identify the charge of a body we should use a charged electroscope. Let us say the electroscope is negatively charged. Now bring the unknown charged body 'X' near the cap of the electroscope. If the leaves diverge more the charge in 'X' must be negative. Suppose that the leaves close a little when 'X' is brought near 'C', then 'X' may have a positive charge or it may not have any charge. In order to confirm the positive charge you must bring the rod 'X' near the cap of a positively charged electroscope. If the leaves diverge more, then 'X' has positive charge.
Why must your touch a charged object to the metal rod of an electroscope and not the rubber stopper?
You must touch a charged object to the metal rod of an electroscope because metal is a good conductor of electricity, allowing the charge to flow through it. The electrons from the charged object redistribute along the metal rod and into the leaves of the electroscope, causing them to repel. Rubber, on the other hand, is an insulator and does not allow the charge to flow.
What makes an object positively or negatively charged?
Step one. Charge the electroscope by the induction method. A rod is used of opposite sign to that required on the electroscope . The rod is brought near to the cap so that the leaf diverges by the amount desired, and the electroscope is momentarily earthed by touching it with a finger. The rod is then removed, leaving the electroscope charged. (If the charged rod used is Benoite this leaves a positively charged electroscope, if a glass rod is used then the result is negatively charged electroscope) Step two Now use the object of unknown charge, A charge of the same kind as that on the electroscope will cause an increase while a charge of the opposite kind will cause a decrease in leaf divergence when the object is brought near to the electroscope. You must bring the object down from a good height, and move it slowly down towards the cap so any change in divergence will not be overlooked before the object becomes to close to the cap. Bringing the object down too quickly and too close to the cap could lead to a false reading. Source(s): A. F. Abott Ordinary Level Physics

If ther are more than conductors in the raceway the ampacity of the conductors must be derated?
Ampacity must be derated depending on the number of conductors and the ambient temperature. In the Canadian Electrical Code Table 5C denotes derating for the number of conductors. 1-3 conductors = 100% load 4-6 conductors = 80% 7-24 conductors = 70% 25-42 conductors = 60% 43 or more conductors = 50%
Conductors emerging from the ground must be enclosed in approved raceways are true or false?
Conductors emerging from the ground must be enclosed in approved raceways. This is to protect the conductors from becoming damaged and starting a fire.
What are five conditions that must be met for running conductors in parallel?
To run conductors in parallel, the following conditions must be met: first, all conductors must have the same length to ensure equal current distribution; second, they should have the same cross-sectional area to maintain consistent resistance; third, the materials used for the conductors must be identical to avoid differences in resistivity; fourth, the conductors should be insulated to prevent short circuits; and finally, the temperature rating of the conductors must be the same to ensure safe operation under varying thermal conditions.
In order for a circuit to function correctly the electricity must do what?
It must flow through the conductors.
How much must be the distance between two conductors of 11kv line?
600mm is the distance between two conductors in 11kv line
Are there electrical fields inside conductors?
if assumed a hollow conductor, it must be INFINITE
How must the radius be changed in order to double the volume of a sphere?
The radius must be increased by 26%. (rounded)
What is relation between voltage and conductors?
Your question is unclear. But, if you are asking what the relationship between voltage and the distance between conductors is, then the higher the voltage, the greater the distance must be.
