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 happens when you open a switch in a series crcuit?
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.
What happens when the circuit is complete and the switches are closed?
*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.
How do you write an hypothesis for open circuit?
open and closed circuits
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.
What determines if a circuit is open or closed?
Closed. If it is open then the power is off.
When the switch is closed it means that?
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.
What is a open switch circuit?
When a switch is 'open' that means it is in the 'off' position. 'Closed' means 'on'.
What is the type of circuit called when it has an conductor a switch a electric cell a resistor?
it is called a circuit and when it is closed is called a closed circuit and when open circuit it is called an open circuit
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 is the difference between open and close switch?
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.
What does a switch look like in circuit symbols?
---o-----o----- is a closed switch / / ---------o o------ is an open switch
What do you mean by open and closed electric circuit?
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.
How must an electrical switch be wired to function with a device?
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.
What is close circuit and an open circuit?
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
When the switch is closed how does the broken wire affect the heating element in circuit A?
If there's a broken wire then the circuit is no longer closed. It's open.
Is an open switch in an electrical circuit to prevent current flow?
Yes, an open switch breaks the circuit and prevents electricity flowing through. A closed switch on the other hand completes the circuit and in turn helps electricity travel through the circuit.
