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.

What happens to an electric current when a circuit is closed?

If the circuit is closed the electric current will be closed as well.


What is a closed path through which current can flow?

A closed path through which a current can flow is called a circuit. Electric Circuit:)


When does the electric current flow?

An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).


What determines if a circuit is open or closed?

Closed. If it is open then the power is off.


In order to have current flow what must a circuit be?

the ciruit must be closed so it can move freely


What kind of circuit allows a current to flow through it?

Closed circuit


What is the evidence that an electrical circuit is closed?

When that circuit has no breaks. It is an endless path of current flow.


What is closed path throuth which current can flow?

An electric circuit.


Why does an electric circuit that operates correctly need to be closed circuit?

In order to have the electricity or the flow or electrons going around the circuit, the circuit must be closed. If it is not closed then electrons cannot flow.


What is the name for the status of a circuit that has breaks which electric current that cant flow?

The name for the status of a circuit that has breaks which electric current that can't flow is called a Closed Circuit. Electric current cannot flow through an open circuit.


What device is needed for current to flow in an electric circuit?

Too vague of a question. As long as it is a closed circuit it will flow.
