Question

what is open circuit and closed circuit example with diagram?​

Answer 1

Explanation:

An open circuit is one where the continuity has been broken by an interruption in the path for current to flow.

A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch.

What is Open circuit?

In Open Circuit, the electric current (charged particles) does not flow from an active energy source to the connected load or other components due to the incomplete path.

If any components disconnect or break from the circuit, this circuit works as the open circuit. Sometimes, the open circuit shows like OFF condition or fault condition.

Example of Open Circuit:-

• Suppose we have connected DC supply battery with the connected bulb as load, resistance and switch.

• When the switch is open, the electric current does not flow from the source (battery) to the desired load (light).

What is Closed circuit?

• In a closed circuit, the electric current (charged particles) flows from an active energy source to the connected load or other components due to the closed-loop path.

For the closed circuit, we require

• conducting materials or conductor (like copper) path.
• the active voltage source device (like a battery).
• complete path or circuit to flow the electric current.

Example of Closed Circuit:-

• Suppose, DC voltage supply battery is connected with the light (like load) and closed switch. Due to closed switch, the circuit makes the complete path to flow electric current.
