What Is an Open Circuit?
Open circuit refers to the state of the circuit when no current passes between two points in the circuit or a conductor with a very large impedance (or resistance) is connected.

- Definition
- No current flows through the circuit or the circuit is disconnected somewhere
- Open circuit refers to the state of the circuit when no current passes between two points in the circuit or a conductor with a very large impedance (or resistance) is connected.
- When the branch between two points in the circuit is open, the potential difference between the two points is called "open circuit voltage" and can be measured with a voltmeter. It is also called open circuit (but there is a difference. Open circuit means that the circuit is not connected; open circuit means that the circuit is not connected somewhere). It means that the resistance of the circuit is infinite due to disconnection at some point in the circuit and the current cannot be normal. Passing results in zero current in the circuit. The voltage at both ends of the interruption point is the power supply voltage, which generally does not damage the circuit. If possible, the wires are broken, or electrical appliances (such as the filament in the bulb) are disconnected from the circuit, etc.
