Basic conductor and current related question

In summary, when a conductor is dyed with red color and connected to a DC source, the current flow through the conductor does not cause the red color to spread because the color comes from the atoms, which do not move even as the electrons flow.

As we say that current is the flow of charges, but if we dye a conductor with red color and then connect the terminal with the dc source.

Now as the current starts flowing through this conductor and we say current is the flow of electrons or charges then why the red color around the conductor doesnot start spreading?

Thanking in anticipation!

hi kambez! :smile:

(what is it with you and colour? :wink:)

the red colour comes from the atoms, and they don't move (and any electrons they lose to the current are replaced by other electrons from the current) :wink:
 

Related to Basic conductor and current related question

1. What is a conductor?

A conductor is a material that allows electricity to flow through it easily. Examples of conductors include metals like copper, silver, and aluminum.

2. What is an insulator?

An insulator is a material that does not allow electricity to flow through it easily. Examples of insulators include rubber, plastic, and glass.

3. How does current flow through a conductor?

Current flows through a conductor when there is a difference in electrical potential, causing electrons to move from an area of high potential to an area of low potential.

4. What is the difference between direct current (DC) and alternating current (AC)?

DC is a type of current where the direction of flow is constant, while AC is a type of current where the direction of flow changes periodically. Most electronic devices use DC, while AC is used for power transmission over long distances.

5. How is current measured?

Current is measured in units called amperes (A), which represent the rate of flow of electricity through a conductor. This can be measured using a device called an ammeter.
