Question

what is open circuit and closed circuit​

Answer 1

$\large{\underline{\boxed{\mathfrak{✦Open\:circuit}}}}$

An open circuit is a path of electricity to paas where the continuity has been broken by an interruption in the path for current to flow. If there is any gap in the path of a circuit, the bulb does not light up. Such a circuit is called an open circuit.

$\large{\underline{\boxed{\mathfrak{✦Closed\:circuit}}}}$

A closed circuit is an electric circuit through which current can flow in an uninterrupted path. The bulb lights up only when a bulb and wire form a complete path, which starts at one terminal of electric cell and ends at the other terminal.

Answer 2

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.
