What do you understand by an electric circuit?

An electric circuit is a closed path or loop through which electric current flows. It allows electrons to move from a power source, through electrical components, and back to the source.

Basic components of an electric circuit:

• Power source: Provides energy (e.g., battery or cell)
• Conducting wires: Allow current to flow
• Load: Device that uses electrical energy (e.g., bulb, fan)
• Switch: Controls the flow of current (open or close the circuit)

Types of circuits:

• Closed circuit: Complete path; current flows
• Open circuit: Broken path; no current flows

How it works:
When the circuit is closed, electrons flow from the negative terminal of the battery, pass through the components, and return to the positive terminal.

Importance:
Electric circuits are essential for operating all electrical and electronic devices.

In simple terms:
An electric circuit is a complete loop that allows electricity to flow and power devices.
