Resistance and Ohms Law When we have a fixed potential

When we have a fixed potential difference then the electric field will also be fixed and therefore there will be a steady electric force on the charge carriers (electrons) - this implies that the carriers should accelerate. In reality, we find that a steady current is maintained. When charge flows i ...
