The current to the load stops flowing and the load device stops operating.
When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.
it prevents electricity to flow. i hope that is right
An open circuit....
A light switch
A switch.
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.
If the switch in a parallel circuit is open, it breaks the circuit and interrupts the flow of current for that particular branch. The other branches in the parallel circuit remain unaffected and continue to operate independently.
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.
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
An open switch circuit is a circuit where the switch is in the "off" position or where the circuit is not complete, preventing the flow of electricity through the circuit. This results in no current flowing and no electrical devices being powered or functioning.
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.
