What else can I help you with?
What determines if a circuit is open or closed?
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.
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)
How much current flows in a circuit with an open circuit?
None.AnswerIt depends! A capacitor is an open circuit, yet a.c. current flows quite readily. And d.c. current will flow for a very short period of time.
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.
When a circuit is opened what happens?
Nothing. An open circuit means no current is flowing. When the circuit is closed, current flows, the filament of the bulb is heated by the current and glows, giving off light. But when the circuit is open, nothing happens.
Which of the circuits will the current flows?
it will open circuit
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.

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.

None.AnswerIt depends! A capacitor is an open circuit, yet a.c. current flows quite readily. And d.c. current will flow for a very short period of time.
What do open and closed circuits have in common?
Both open and closed circuits involve the flow of electric current. In an open circuit, the current is interrupted or stopped due to a gap in the circuit, while in a closed circuit, the current flows continuously through a complete loop of conductor.
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.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
