If you are using a multimeter as an ohmmeter, then turn the dial to the ohm scale. On a digital meter you will see a reading of 0L. This is the reading that you would see if the circuit is open, as in fact the circuit is open at this point in time. If you touch the leads together then you would see a reading of 0 which is a correct reading of 0 ohms.

What determines if a circuit is open or closed?
Closed. If it is open then the power is off.
What is through a discontinuous circuit which no current can flow?
meaning that the current from your power source doesn't return to the positive end (electricity flows from - negative, to + positive)
When current flows to all parts of a circuit the circuit is open?
Current only flowes in a closed circuit. Electrons have to have a complete path from the negative side of the source to the positive side.
How a circuit breaker prevent from too much current flowing into device?
The current (in question) flows through both the circuit AND the circuit breaker [they are in series]. Within the circuit breaker when the current exceeds the preset limit it will open the circuit thus stopping all current flow. There are two common ways of doing this 1) magnetism - a coil pulls a switch open 2) thermal - a bimetallic strip bends away from its contacts, which opens the circuit.
Is the neutral wire energized when the appliance is off?
No current flows in the circuit when the circuit is open, as in when the appliance is switched off. The voltage is on the "hot" side of the switch when it is in the open position but the neutral is not energized until the switch is closed.
What device used to open a circuit if too much current flows through it?
A circuit breaker is a device used to open a circuit if too much current flows through it.
Which of the circuits will the current flows?
it will open circuit

When dangerously high current flows through this overheated metal pushes the switch open to create an open circuit What is this?
A circuit breaker.
If a fuse melts does it create an open circuit a closed circuit or a short circuit?
If a fuse melts, it creates an OPEN circuit, meaning that no current flows in the wires because it is no longer a complete circuit.
When current flows to all parts of a circuit the circuit is open?
Current only flowes in a closed circuit. Electrons have to have a complete path from the negative side of the source to the positive side.
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 is infinity resistance?
That's an "open circuit". No current flows no matter how high the voltage gets. It doesn't exist in nature.
Do electric charges flow all the way through on open circuit?
No, nothing flows through an open circuit. If there are two flat plates on either side of the open circuit, facing each other, electric charge builds up on each plate until the plates are at the supply voltage. If the voltage is AC, current will flow all the time as the voltage changes, because the flat plates form a capacitor that can pass AC. But there is no net power.

When a lamp is switched off is the electrical current to the light open or closed?
Open and closed does not refer to electrical current or the flow of electricity. Open or closed refers to the state of an electrical circuit. When a lamp is turned on electricity flows through wires, the switch and the lamp; and the circuit is considered closed. When a lamp is switched off the circuit is considered open (or broken) and the flow of electric current is stopped.
