a closed circuit
You can test if something is an insulator or conductor by connecting a circuit with a power source and a light bulb. If the material allows the light bulb to turn on, it is a conductor. If the light bulb does not turn on, it is an insulator.
When you turn off a light, you are breaking the circuit that allows electricity to flow through the light bulb, causing the light bulb to turn off. The electricity in the circuit is still present and will continue to flow until the power source is disconnected or turned off.
When you turn off the wall switch, it breaks the circuit that allows electricity to flow to the light bulb, causing the light to go out.
A circuit that can turn off a light bulb is typically a simple open circuit. When a switch is opened, it interrupts the flow of electricity, preventing current from reaching the light bulb and causing it to turn off. Alternatively, a circuit with a relay or a timer can also be used to control the on/off state of a light bulb.
When you turn on a light switch in a room, it closes the circuit. This allows electricity to flow through the wiring to the light fixture, illuminating the bulb. Conversely, turning off the switch opens the circuit, stopping the flow of electricity and turning off the light.
If a light bulb is touched by a conductor to complete the circuit, it will turn on if the circuit is closed and working properly. The conductor helps to create a path for the electricity to flow from the power source to the light bulb, allowing it to illuminate.
The paper will not conduct electricity, so it will not light up the bulb. The pencil lead, on the other hand, can conduct electricity and complete the circuit, causing the light bulb to turn on.
When you unscrew a light bulb in a series circuit, the circuit will break and all the other light bulbs in the circuit will turn off. This is because in a series circuit, the current flows through each component in succession, so removing one component interrupts the flow of current to the rest of the circuit.
you can make the light bulb turn on. Ooh ooh i know. it's a circuit!
A closed switch completes the electrical circuit, allowing current to flow through the light bulb and generate light. If the switch is not closed, there is an open circuit, meaning the current cannot flow and the light bulb does not turn on.
The light bulb in the circuit turns on due to the flow of electric current, which is facilitated by a closed circuit. When the switch is closed, it completes the circuit, allowing electrons to move from the power source through the bulb, causing it to emit light. The resistance in the bulb converts electrical energy into light and heat, resulting in illumination.
The glass of the light bulb is not conductive, so the circuit would not be completed. You would need to join the wires to the positive and negative contacts on the base of the bulb for the circuit to work.
