Question

which device is used to Veri potential difference without the removal of the battery​

Answer 1

Answer:

When we apply a battery to the ends of a conductor then due to the potential difference between the ends of battery free electrons in the conductor move and respond to the external electric field applied. So, we can say that without potential difference there is no concept of current flow.Nov 14, 2013
