So you can turn it on... and you can turn it off...!
A voltage or current source in series with a circuit breaker or fuse in series with a switch in series with a light bulb.
If the switch in a parallel circuit is open, it breaks the circuit and interrupts the flow of current for that particular branch. The other branches in the parallel circuit remain unaffected and continue to operate independently.
A switch is placed in an electrical circuit in order to place a gap when the switch is off, so the circuit is broken. When the switch is on, the circuit is complete and the electricity can flow round the circuit.
Overloaded circuit, short in circuit, or defective switch.
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
The switch needs to be in the "on" position for the circuit to work, allowing the flow of electricity through the circuit. In the "off" position, the switch breaks the circuit, stopping the flow of electricity.
Take the light out. You might have a bad switch in the door frame. When the door closes- it pushes a switch which I believe opens a circuit and shuts off your light. If the switch is bad it wont open the circuit and the light stays on.
For an electrical circuit to keep going, it cannot be interrupted. When the switch is adjusted, the electrical flow is interrupted. Move the switch again and the flow is restored. Without a switch a circuit is no longer considered a complete circuit. Simple fifth grade science.
Not sure what you mean with "lemon circuit", but in an electrical circuit, the switch can be just about anywhere.
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
A switch is a device used to break a circuit. By opening the switch, the circuit is interrupted and electricity stops flowing. This allows for controlling the flow of electricity to different components in a circuit.
Closing a switch makes a closed circuit Opening a switch opens, or breaks the circuit
