The electrons move( -ve) to (+ve) then why the current flows from (+) to (-)❓ |
|
Answer» In an electric circuit, the direction of flow of electron is taken to be from negative to positive but the direction of current (say conventional current) is taken from positive to negative. When electricity was discovered, scientists at that time were not aware of electrons. They thought that positive ions were responsible for conduction of current. Therefore, they decided that the direction of current would be from positive to negative. We still respect this convention even today. so we named it conventional current direction. The great scientist J. J. Thomson when discovered electrons. Then everyone soon understood that electrons were responsible for current in most conductors. to change the previous convention was not a good idea. Hence, we continued to use the same convention. |
