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.

When a switch is on is a circuit open or closed?
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
Why will a bulb not light if a switch is open in a circuit?
It will not work because it has to be closed so the electricity can go to the bulb.
What device will open or close the break in a electrical circuit?
A switch.
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.
Will an open switch record a resistance of zero ohms?
no...... ideal open switch should have a resistance of infinity... the question should be a closed switch http://wiki.answers.com/Q/Will_an_open_switch_record_a_resistance_of_zero_ohms" but this is also false because any good conductor will have a small resistance the connecting wire resistance is exhibitted across the terminals of the switch
What happens if the switch is open?
If the switch is open, current does not flow.
What happens if the switch is open in a parallel circuit?
It shouldn't. Your house wiring is a series- parallel circuit.
How does a kill switch work?
The KILL switch is in series with the ignition switch. When the KILL switch is open, the bike will not start.
Can series circuits work when a switch is open?
No. Since the switch is in series with the circuit, opening it blocks the current flow through the circuit, turning it off.
What happens to an electric current at a light switch?
When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.
What happens if there is a break in a series circuit?
The series circuit becomes an open circuit because there is no remaining path.
What happened what happens when a switch in a circuit is open?
it prevents electricity to flow. i hope that is right
5 An M-series switch is reset to factory default and open Trunking becomes inoperableHow do you solve the problem?
disconnect and reconnect the switch
What happens if you move a switch and the circuit wires are not all connected?
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.
What happens when you open a switch in a circuit?
The current to the load stops flowing and the load device stops operating.
Why are series circuit used for most control circuit?
Because The opening of any switch in a series circuit will open the circuit and stop the flow of current to the load
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
