When was the invention completed?

the light bulb!


What happens to the bulb when the circuit is completed?

Shouldn't it light?


What property must the liquid have in order for the bulb to light up?

The liquid must be a conductor of electricity in order for the bulb to light up. If the liquid does not conduct electricity, the circuit will not be completed and the bulb will not illuminate.


Why does a battery power a light bulb?

A battery powers a light bulb by converting stored chemical energy into electrical energy. When the battery is connected to the light bulb, a circuit is completed, allowing the flow of electrons through the filament of the bulb, which produces light and heat.


What will happen if you try to complete a circut by joining the glass of a light bulb to the batttery?

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.


Why the bulb is not lighting when one wire or terminal is not connected?

When one wire or terminal is not connected to a light bulb, it is not possible for electricity to complete the circuit. When a circuit is not completed, the bulb will not light. An off switch, for example, breaks the circuit.


Does an empty bulb holder conduct electricity?

No, why because know, In an empty bulb holder the circuit is not completed and there for the flow of electrons will not take place obviously the current passage won't be there.


What does the electrical foot contact do in a light bulb?

The electrical foot contact in a light bulb serves as a connection point for the electrical current to flow into the bulb. It ensures that the electrical circuit is completed when the bulb is screwed into a socket, allowing the filament or LED components to illuminate. This contact is essential for the bulb's operation, enabling it to produce light when powered.


How can energy get to a light bulb?

Electricity flows through a wire connected to the light bulb, providing the energy needed to illuminate it. When the circuit is completed, electrons move through the wire and generate light and heat in the bulb through the process of electrical resistance.


If a light bulb is missing in a series circuit will the bulb light?

If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.


Which makes the conducting link between the cell and the bulb in the torch?

The conducting link between the cell and the bulb in a torch is the wires inside the circuit. When the switch is turned on, the circuit is completed, allowing the electrical current to flow from the cell through the wires and to the bulb, causing it to light up.


What can be inferred about the currentbpassing through the bulb?

We can infer that current is needed to generate Electrical appliances and also to make the flow of electric circuits be completed.
