When the switch is turned it completes an electrical circuit. The circuit amperage flows through a high resistance filament in the bulb and it starts to glow. The bright glow from the filament and the reflector behind the bulb is what creates the flashlights beam.

Do you have a diagram on 9volt battery and light bulb?

Draw a battery and light bulb. Draw a line from the smaller connector on the battery to the bottom of the light bulb, this is positive on both. Draw a line from the bigger connector on the battery to the side of the light bulb,'this is the negative of both. Looked all over and can't seem to find this one.


What is the controlled variable for a light bulb and battery?

The controlled variable for a light bulb and battery experiment would be the type of light bulb or battery used. Keeping these variables constant ensures that any changes in the experiment are due to the independent variable being tested.


How can you use a wire battery and a light bulb to test an item to see if it is a conductor of electricity?

I am going to assume you meant Three wires, Battery and Light Bulb. (punctuation and plurals are important) Hook the light to one post of the battery Hooked from the light to the item being tested (use the other light connection, not the one connected to the battery) connect the other end of the test item to the unused terminal on the battery. Light comes on means it conducts electricity No Light, it does not.


Does a 9 volt battery light a light bulb?

Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.


Would you expect to find direct or alternating current in the filament of a light bulb in your home the filament of a light bulb in a car the output of a battery charger?

Light bulb in the home - alternating current (A/C) Light bulb in a car - direct current (D/C) Output of a battery charger - direct current Input of a battery charger - usually alternating current

What happens when you connect a single battery to a light bulb?

If the voltage is appropriate, the bulb will shine.


What happens to a bulb when you move it to the battery on a circuit?

It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.


What happens when you connect the battery's negative side to the ground with a light bulb will it light up?

Nothing happens at all, unless there is a complete conducting path back to the battery's positive side. Once you have that, current will flow, and the light bulb may light up.

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 happens when you flip a switch on a flashlight?

When you flip a switch on a flashlight, you complete an electrical circuit that allows a current to flow from the battery to the light bulb. This causes the light bulb to emit light and illuminate the surroundings.


What happens when a bulb is attached to a battery?

When a bulb is attached to a battery or a cell as scientists call it, the bulb glows. If you want a bulb to glow more and more brighter, it depends on how many batteries you attached to the bulb. If you attach a lot of batteries at the same time, the bulb might even explode or burn out. The wires that hold the interaction between a light bulb and the battery is electricity. The electricity flows through the wires and touches the bulb and that is how a light bulb glows.


How does a simple circuit with a battery and a light bulb work?

In a simple circuit with a battery and a light bulb, the battery provides electrical energy that flows through the wires to the light bulb. The electrical energy causes the filament in the light bulb to heat up and emit light. This process continues as long as the circuit remains closed and the battery has power.


How do you make a light bulb light up using a 1.5 volt battery?

If it is a 1.5 volt bulb you can connect it through a series circuit directly to your battery. If the bulb is not made to run on 1.5 volts and needs another voltage, it may not light up!


What components do you need to make a simple series light bulb?

You need a Battery, Light Bulb, Ammeter, Switch.


What happens to a bulb when you move it closer to a battery on a circuit?

The bulb will get brighter


If you connect a battery and a bulb in this way the bulb will not light?

yes
