Closing a switch makes a closed circuit
Opening a switch opens, or breaks the circuit
When you turn on a lamp, you are closing the circuit. This allows electricity to flow from the power source, through the lamp, and back to the power source, enabling the lamp to light up.
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.
An electrical circuit is a path which electrons from a current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load". ---Nerd
Assuming you are talking about electrical circuits: "Cell" is the name given for a battery. Without a cell in the circuit, there is no supply of electricity. Therefore there is no electric circuit.
The letters "NC" on an electrical switch stand for "Normally Closed." This means that in the default position, the circuit is closed and allows electricity to flow. When the switch is activated, the circuit opens and interrupts the flow of electricity.
Charges in a circuit move in response to an electric field created by a power source like a battery. This electric field exerts a force on the charges, causing them to move through the circuit. This movement of charges is what allows electrical energy to be transferred from the source to the electrical components in the circuit.
An electric circuit.
A switch in an electrical circuit controls the flow of electricity by opening or closing the circuit. When the switch is closed, it allows electricity to flow through the circuit, completing the path for the current. When the switch is open, it interrupts the flow of electricity, breaking the circuit and stopping the current from moving through.
The power source, typically a battery or a generator, supplies the potential difference in the circuit. This potential difference allows charges to flow through the circuit and power the electrical components.

Any complete circuit. ==== An electrical circuit.
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.

Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current.AnswerAn interesting question. The answer is.... not necessarily! I say this because a capacitor is an open circuit, yet it allows d.c. current to flow for a short period of time (while it charges), and it allows a.c. current to flow continuously.
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
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.
