In an electric circuit, the direction of electric current is from the positive terminal of the battery to the negative terminal of the battery. This is as per convention. Electrons were not known at the time when the phenomenon of electricity was first discovered. Electric current was considered to be the flow of positive charges and the direction of flow of positive charges was taken to be the direction of electric current.

The Direction of Electric Current in an Electric Circuit
In an electric circuit, the direction of electric current refers to the flow of electric charge. Electric current is the rate at which electric charges flow through a conductor, such as a wire. The direction of electric current is determined by the flow of electrons, which are negatively charged particles.
Convention of Electric Current Direction
The convention for determining the direction of electric current is based on the flow of positive charges, even though the actual flow of charge is due to the movement of negatively charged electrons. This convention was established before the discovery of electrons and is still widely used today.
According to the conventional flow of electric current, it is considered to flow from the positive terminal of a battery or power source to the negative terminal. This means that the direction of electric current is opposite to the flow of electrons.
Positive Terminal to Negative Terminal
The correct answer to the question is option 'C': from the positive terminal to the negative terminal. This means that when a circuit is connected to a battery or power source, the electric current flows from the positive terminal of the power source, through the circuit components, and returns to the negative terminal.
Benefits of the Conventional Flow Convention
While the conventional flow convention may seem counterintuitive, it is still widely used in electrical engineering and circuit analysis. This convention allows for consistency and simplifies the analysis of electrical circuits. By considering the flow of positive charges, engineers and scientists can easily determine the behavior of circuits and make accurate calculations.
Summary
In summary, the direction of electric current in an electric circuit is from the positive terminal to the negative terminal, according to the conventional flow convention. This convention allows for consistency and simplifies circuit analysis, despite the actual flow of negatively charged electrons.
