it prevents electricity to flow. i hope that is right
When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.
When a switch is open (wires not connected) it is considered off. When a switch is closed it is considered on. If you move a switch and the wires are not connected the the circuit is open and current cannot run throughout the circuit to power the device.
An open circuit....
It shouldn't. Your house wiring is a series- parallel circuit.
A light switch
A switch.
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
The current to the load stops flowing and the load device stops operating.
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
When you turn on a light switch you do not have an open circuit.
A closed series circuit is one where the current flows through all devices in the circuit. Opening a switch prevents current from flowing in the circuit and it becomes simply an "open circuit". Any device that operates with current (light, LED, motor, etc) will no longer function.
It open and close it
