When a switch is turned from the off to the on position, it is changing the circuit in which of the following ways?

I love Jiskha

When a switch is turned from the off to the on position, it is completing the circuit. In the off position, the circuit is open, meaning that there is a gap or interruption in the flow of electric current. When the switch is turned on, it closes that gap and allows electric current to flow freely through the circuit. This allows electrical devices connected to the circuit to receive power and operate.

When a switch is turned from the off to the on position, it is changing the circuit from an open circuit to a closed circuit.

To understand this, let's start with the basics of a circuit. A circuit is a closed loop path through which electric current can flow. In a closed circuit, the current can flow continuously. In contrast, an open circuit does not allow the current to flow because the path is broken.

A switch is a device used to control the flow of electricity in a circuit. When the switch is in the off position, it creates an open circuit. This means that the electric current cannot flow through the circuit, as the path is disconnected.

However, when the switch is turned on, it creates a closed circuit. This allows the electric current to flow from the power source, through the switch, and along the circuit, reaching any devices or components connected in the circuit.

So, by turning the switch from the off to the on position, you are changing the circuit from an open circuit (no current flow) to a closed circuit (current can flow).

I bet current flows through the complete circuit.
