How does current flow in a circuit?

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Circuit**: A circuit is a closed loop that allows electric current to flow. It consists of various components such as a power source (like a battery), wires, and devices (like bulbs).

2. **Closed Circuit**: When the circuit is closed (the switch is ON), it forms a complete path for the current to flow. In this state, the electric current can travel from the positive terminal of the battery, through the circuit, and back to the negative terminal.

3. **Direction of Current Flow**: The conventional direction of current flow is from the positive terminal to the negative terminal of the battery. This means that the current flows out of the positive terminal, through the circuit, and returns to the negative terminal.
