The direction of flow of electric current in an electric circuit is

Options

A. positive to negative
B. negative to positive
C. positive to positive
D. negative to positive

Explanation

To determine the direction of flow of electric current in an electric circuit, follow these steps:

### Step-by-Step Solution:

1. **Understanding Electric Current**: Electric current is the flow of electric charge in a circuit. It is important to know the conventional direction of this flow.

2. **Identify the Components of the Circuit**: In a typical circuit, you have a power source (like a battery or cell), a load (like a bulb), and a switch. The power source has two terminals: a positive terminal and a negative terminal.

3. **Conventional Current Direction**: The conventional direction of electric current is defined as the direction in which positive charges would flow. This means that current is considered to flow from the positive terminal of the power source to the negative terminal.

4. **Conclusion**: Therefore, in an electric circuit, the direction of flow of electric current is from the positive terminal to the negative terminal.

5. **Final Answer**: The correct answer is that the direction of flow of electric current in an electric circuit is from **positive to negative**.
