Flow of current. Conductors and Insulators.

In summary, when two neutral conductors touch, no current will flow. However, when a neutral conductor touches a positive conductor, current will flow from the neutral to the positive conductor. Similarly, when a negatively charged conductor touches a positively charged conductor, current will flow from the negative to the positive conductor. On the other hand, if a neutral conductor touches a positive insulator, there will be no current flow.

This is NOT a homework question.. It is just something that is bothering me...

1. If two neutral conductors are made to touch each other, no current will flow..
2. If a neutral conductor is made to touch with a positive conductor, the current will flow from the neutral to the positive conductor...
3. If a negatively charged conductor is made to touch with a positively charged conductor, the current will flow from the negative to the positive conductor..
4. If a neutral conductor is made to touch a positive insulator, the current will not flow...

Which of these is true?? This is really confusing me... Please help, I need it...

It may not be a homework problem, but it looks an awful lot like a take-home test. What part exactly are you confused on?
 

1. What is the flow of current?

The flow of current is the movement of electric charge through a conductive material. It is measured in amperes (A) and is also known as electric current.

2. What are conductors and insulators?

Conductors are materials that allow electric charges to flow through them easily, while insulators are materials that resist the flow of electric charges. Conductors typically have free electrons that can move around, while insulators do not.

3. What makes a material a good conductor?

Materials that are good conductors typically have a high concentration of free electrons, allowing for easy movement of electric charges. They also have low resistance, meaning that there is less hindrance to the flow of current.

4. What are some common examples of conductors and insulators?

Some common examples of conductors include metals such as copper, aluminum, and silver. Insulators include materials such as rubber, plastic, and glass.

5. How does the flow of current differ in conductors and insulators?

In conductors, the flow of current is typically high and easy, due to the presence of free electrons. In insulators, the flow of current is much lower, as the material does not have as many free electrons and resists the flow of electric charges.
