Question

3. (i) Explain the electric current on the basis of free ele
tron model. How can determine the direction of flow of current? Please solve
​

Answer 1

Answer:

direction of current is opposite to direction of flow of electrons

Answer 2

Answer:

In an atom, the electrons move around the nucleus whereas protons remain bounded in the nucleus.

During the formation of metallic materials, these electrons get separated from their parent atoms and move in a random manner in the conductor. Such electrons are known as 'Free electrons' .

These free electrons are responsible for the conduction of electric current.

The direction of current can be determined when current flows from positive to negative terminal in the circuit . This flow is also known as conventional current.
