What happens when a conducting sphere rubs against metal?

In summary, the rubbing of a conducting sphere against metal is typically caused by an external force and can result in the transfer of electrons, creating static electricity and potentially generating heat. The electrical charge of the objects is affected as the conducting sphere gains electrons and the metal object loses them. The outcome may vary depending on the materials used for the conducting sphere and metal.

I know that metal is a "reservoir" of electrons, whereby electrons can flow out and in easily, so when conducting sphere is rubbed against metals, is there even a resulting charge on the conducting sphere?

I think there will not be a fixed charge on conducting material
 

1. What causes the conducting sphere to rub against metal?

The conducting sphere and metal may come into contact through various means such as friction, electrostatic attraction, or physical movement.

2. What happens to the charge on the conducting sphere when it rubs against metal?

The charge on the conducting sphere may transfer to the metal, depending on the materials and conditions involved. This can result in a change in the charge distribution on both objects.

3. Does rubbing a conducting sphere against metal generate electricity?

Yes, rubbing a conducting sphere against metal can generate electricity through the transfer of charge. This is known as the triboelectric effect.

4. Can rubbing a conducting sphere against metal cause sparks?

Yes, rubbing a conducting sphere against metal can cause sparks due to the transfer of charge and the buildup of static electricity. This can be seen in everyday occurrences such as when you rub your feet on carpet and touch a metal doorknob.

5. How does the rubbing of a conducting sphere against metal affect its conductivity?

The rubbing of a conducting sphere against metal can affect its conductivity by altering the charge distribution on both objects. This can change the flow of electrons and impact the overall conductivity of the materials.
