Question

Direction of electric current inside the cell is from
A. Positive electrode to negative electrode
B. Negative electrode to positive electrode
C. Positive electrode to positive electrode
D. Negative electrode to negative electrode

Answer 1

Hint: We need to find the direction of electric current in a cell. For that let us consider a situation of a cell connected in a circuit. We know that one end of the cell is positive terminal and the other end is negative terminal. Electric current will move from one of the terminals to the other and the electrons will move in the opposite direction of the movement of the current.

Complete answer:
We have a cell and we need to find the direction of electric current in the cell.
For that let us consider an electric circuit connected across a cell as shown in the figure below.

Terminal A is the positive electrode and terminal B is the negative electrode of the cell.
We know that in an electrical circuit the direction of flow of the electrons is from the negative electrode to the positive electrode, i.e. because the negative charged electrons originate from the negative terminal of the cell.
And we also know that the direction of flow of current in a circuit will always be opposite to the direction of flow of electrons.
Therefore, the electric current inside the cell will move from positive electrode to negative electrode.

Hence the correct answer is option A.

Note:
We know that the direction of the electric current is the direction of the positive charge.
And as we know the positively charged ions originate from the positive terminal of the cell.
Therefore the positive charges move from positive terminal to negative terminal and hence the current flows from the positive electrode to the negative electrode.
