How Current Flows in Conductor

How Does Current Flow In Conductors|Drift Velocity And Current Electricity

Assertion : Current flows in a conductor only when there is an external electric field within the conductor. Reason: The drift velocity of the electrons is directly proportional to the electric field.

When a current flows in a conductor, the order of magnitude of drift velocity of electrons through it is :

Assertion: A current flows in a conductor only when there is an electric field within the conductor: Reason: The drift velocity of electron in presence of electric field decreases.

Mention the condition under which a current can flow in a conductor .

State the relation correlating the electric current flowing in a conductor and the voltage applied across it. Also draw a graph to show this relationship.

What is meant by Joule's heating effect due to flow of current through a conductor?

The resultant force on a square current loop PQRS due to a long current carrying conductor will be (if the current flow in the loop is clockwise)
