What is Open, Short, and Closed Circuits 

A circuit is a path that electricity follows to power devices and systems. It is made up of wires, conductors, and other components that allow the flow of electrical current

Open Circuits An open circuit is one that is incomplete or broken. In other words, there is a gap in the circuit that prevents the flow of electricity. This gap can be caused by a disconnected wire, a blown fuse, or a switch in the "off" position. When an open circuit occurs, devices that rely on the circuit to work will not function properly, or not at all. One example of an open circuit is a light switch that is turned off. The switch disconnects the circuit, causing the light to stop functioning. Another example is a disconnected wire in a stereo system, which can cause one or more speakers to stop working. Short Circuits A short circuit is one that has low resistance due to an unintended path for the flow of electricity. Essentially, the circuit takes a shortcut, bypassing the devices or systems that are meant to regulate the flow of electricity. This can cause a surge in electrical current that can be dangerous, and even cause fires. A short circuit can occur when two wires touch that shouldn't be touching, or when a wire is exposed and comes into contact with a conductive material. Short circuits can also occur due to damaged devices or systems, such as a damaged capacitor in a computer's power supply. Closed Circuits A closed circuit is one that is complete, with no gaps or unintended paths for the flow of electricity. This allows the current to flow smoothly through the circuit, powering devices and systems as intended. Closed circuits are the most common type of circuit and are essential for devices and systems to function properly. One example of a closed circuit is a simple flashlight. When the switch is turned on, the circuit is closed, and the flow of electricity powers the light bulb, allowing it to emit light. Another example is a television, where a closed circuit is used to power the screen and the various components of the television.
