What happens to the electric current when the potential difference is zero?
When the potential difference is zero then:
What happens to the flow of charges when the potential difference between two points becomes zero?
Electric current will stop flowing when the potential difference is:
the potential difference b/w the terminals of an electric heater in 60V when when iT DRAWS CURRENT of 4A from the source . What current will the heater draw if the potential difference is increasedto 120V
