Question

The conventional direction of flow of current is

• A. negative terminal to positive terminal of the cell.
• B. positive terminal to negative terminal of the cell.
• C. opposite direction of electrons
• D. in direction of electrons.

Answer 1

Answer: (B), (C)

positive terminal to negative terminal of the cell.
opposite direction of electrons

The current in the wire is due to the drifting of electrons inside a wire in a direction opposite to the flow of electrons. During their drifting they collide with their atoms vibrating about their mean position and lose some of kinetic energy to the vibrating atoms.
The electrons are negatively charged particles and so, the electrons move towards the positively charged terminal from the negatively charged terminal.
Hence, the statement is true as the conventional direction of flow of current is from positive terminal to negative terminal of the cell.
