If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
It will not work because it has to be closed so the electricity can go to the bulb.
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.
*Look at the simple circuit illustrated in Figure A-2. What will happen when only switch S1 is closed? Correct Answer= "Nothing will happen-the light bulb won't light up." <<>> If there is a load in the circuit the load will operate. If there is no load in the circuit and it is complete then a short circuit will occur and something in the circuit will burn open. If the circuit is complete and there is a fuse or breaker in the circuit, then the fuse or breaker will open the circuit.
open and closed circuits
A switch is a device that is used to open and close an electrical circuit that is is connected into.
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.
A circuit is considered open if there is a gap in the path for electricity to flow, causing the current to stop. A circuit is closed when there is a complete, unbroken path for the electrical current to travel through.
It will not work because it has to be closed so the electricity can go to the bulb.
A switch in circuit symbols is represented by a break in the line with a gap or by a line that can be closed to complete the circuit. It typically looks like a gap that can be closed or opened to control the flow of electrical current in a circuit.
In an open circuit no cuttent can flow so the switch would have to be in the off position- the switch is open and not completing the circuit. A closed circuit is one where current can flow all the way through, the switch would have to on and therefore closed.
A circuit will not work if a switch is open, be because it is not allowing the electricity to flow. Where as if it was closed it would give the electricity a sealed off path to flow through.
An open circuit is one where the current is not able to complete the circuit. An example could be a light bulb connected to power but switched off, the circuit being broken by the switch, and considered "open." When flipping the switch On, it connects the power and the circuit is then closed.
Switches control the flow of electric current in a circuit. In an open circuit, the switch is off, interrupting the flow of current. When the switch is closed in a closed circuit, it allows the current to flow continuously through the circuit.
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.
A switch, circuit breaker, fuse, or switching transistor can do that.
So that when the switch is in the open position the circuit is open and electricity cannot complete the circuit. When the switch is closed it completes the circuit and electricity flows completing the circuit and powering the device.
a closed circuit is a complete circuit with no breaks at all, one example:- a closed circuit occurs when you turn the light switch on an open circuit has a physical break in the circuit, which stops the flow of electrons. one example is when the lights are turned off, the switch creates a physical break in the circuit
