If everything is working as it should then no current flows when the breaker is off. This is no better example of this than there is on answers. When a do it yourselfer looks for an answer and gets one, the answer is always ended with the suggestion that before doing any work always shut off the breaker.
If the breaker is malfunctioning one symptom is that a voltage is still present even though the handle is in the off position. If this is the case change the breaker out immediately.

What restricts the flow of energy?
You can change current by altering potential difference or resistance... But assuming the voltage is constant, the resistance of the circuit restricts the flow of electrical current.
Why must a circuit be closed in order for current to a 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.
In a circuit the purpose of a switch is to?
In a circuit, the purpose of a switch is to control the current flow to the load by opening the circuit (off) or closing the circuit (on). When the circuit is open, the is no complete loop through which the current can flow. When the switch closes the circuit, it restores the loop, and thus allows the current to flow.
How a fuse controls the flow of electric current in a circuit?
A fuse does not control the flow in a circuit, it limits the current in a circuit. If the load in a circuit shorts out the fuse link melts and opens the circuit and stops the current flow and prevents the wires feeding the circuit from melting and catching fire. resist
What happens to an electric current when a circuit is closed?
If the circuit is closed the electric current will be closed as well.

The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
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:)
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.

In a circuit, the purpose of a switch is to control the current flow to the load by opening the circuit (off) or closing the circuit (on). When the circuit is open, the is no complete loop through which the current can flow. When the switch closes the circuit, it restores the loop, and thus allows the current to flow.
What is the difference between a series electric circuit?
A series circuit is a circuit that only has one path for current to flow on, a parallel circuit is a circuit that has multiple paths for current to flow on. Parallel circuits are mostly used, especially in your house/home. The reason of that is because, if a device in a series circuit electrically malfuctions or goes down, it will stop the current flow, thus ending and cuting the whole rest of the circuit. In a Parallel circuit, if a device electrically goes down, current will still be able to flow through the other circuit branches, and the rest of the circuit, thus keeping electricity flowing.

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 is a circuit with two or more branches for current to flow called?
Parallel circuit
