The direction of the flow of current through electric circuit is

Options

A. from low potential to high potential.
B. from high potential to low potential.
C. does not depend upon potential value
D. current cannot flow through circuit.

Answer

### Step-by-Step Solution:

1. **Understanding Current**:
- Current is defined as the flow of electric charge. In most cases, this charge is carried by electrons in a conductor.

2. **Identifying Potential Difference**:
- For current to flow, there must be a potential difference (voltage) between two points in the circuit. This potential difference creates an electric field that drives the movement of charges.

3. **Direction of Charge Flow**:
- Charges flow from a region of higher electric potential to a region of lower electric potential. This is due to the natural tendency of charges to move towards a state of lower energy.

4. **Conventional Current Direction**:
- By convention, the direction of current is taken to be the direction in which positive charges would flow. Therefore, conventional current flows from the positive terminal (higher potential) to the negative terminal (lower potential) of a power source.

5. **Spontaneous Process**:
- The flow of current is a spontaneous process, meaning it occurs naturally when a potential difference is applied, without the need for external intervention.

### Final Answer:
The direction of the flow of current through an electric circuit is from the region of higher potential to the region of lower potential.
