Question: What happened to the flashlight when you put the battery back on?

A: If the flashlight makes light when you switch it on, then the batteries are not completely depleted of energy. The light bulb is just a thin wire of tungsten in a glass bulb with the air taken out, and it doesnt really care which way the electricity flows.

What happen when you switch on the flashlight with battery?

When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. When activated by electricity, the tungsten filament or LED in the lamp begins to glow, producing light that is visible.

Which energy transformation happens when you switch on the flashlight?

In a flashlight, the electrical energy becomes light energy and thermal energy in the bulb.

What causes a flashlight to stop working?

Double-Check Your Power Source The first thing you should always do if your flashlight is not working is double check the batteries. Even if youre sure you put new, fresh batteries in your device, swap them out. You never know if its a simple problem until you try a simple solution. If the problem persists, move on.

How do batteries go in flashlight?

So where the springMoreYou can get the light in there theres a little spring down there at the bottom. So where the spring goes is generally. Where the flat edge goes so you want to put that down in there.

What happens when the switch of the flashlight is turned off?

When you move the switch to shut off your flashlight, you disconnect the wires that run from the battery to the light bulb. When you turn off your flashlight, you put the switch in what is called the open position. With the switch in the open position, you have a disconnected wire, and no current can flow.

What does the flashlight represent?

Earth -- The small globe represents the Earth and a flashlight represents the Sun.

Do you think matter is lost or conserved when you use a flashlight?

produces chemical energy. Batteries can convert stored chemical energy into electrical energy. In a flashlight, the electrical energy becomes light energy and thermal energy light bulb. so the answer would be yes It does.

How can heat and light energy be transformed?

The heat energy may be converted into kinetic energy in a gas turbine and finally into electrical energy by a generator. The electric energy may subsequently be converted into light, sound or kinetic energy in our homes through various household appliances.

Why is my handheld flashlight not working?

If your flashlight has a dim or weak light or simply wont turn on, it could be the battery. Check the battery in the flashlight to make sure that it still has charge in it. You might just have to replace or charge the battery. Another issue can arise with the o-ring if your flashlight has a tactical ring.

Which end of battery goes to spring?

As you insert the negative end of the battery, you may press down a spring or a lever. By installing the negative end first, the battery will slide into the compartment more easily.

Where does electricity go when you turn it off?

As for the power dissipated in the wires, at least for well-behaved loads that basically scales with the amount of work they are moving from one place to another, so when you turn off the light, most of the power lost along the way in moving that work to you stops being lost as well.

What happens when a switch is turned on?

With the switch in the open position, you have a disconnected wire, and no current can flow. When you turn on the flashlight, you put the switch in the closed position. With the switch in the closed position, youve connected the wire (and completed the circuit), and current can flow.

What are the uses of flashlight?

Flashlights are used as a light source outdoors, in places without permanently installed lighting, during power outages or when a portable light source is needed. In addition to the general-purpose hand-held flashlight, many forms have been adapted for special uses.

What happens in terms of energy when a moving car hits a parked car?

What happens in terms of energy when a moving car hits a parked car, causing the parked car to move? The moving car transfers kinetic energy to the parked car. Kinetic energy in the moving car disappears.

Why is energy needed to be transformed into another form?

To be useful energy needs to be stored in some forms to be transformed into other forms. We often transform these into heat and then mechanical/kinetic and then perhaps electrical energy. In hydroelectric dams, energy is stored as gravitational potential energy to be converted into kinetic and then electrical energy.

At what temperature does heat energy start changing to light energy?

Answer: All matter emits “light”. The night sky where it is total black, is still emitting at about 2.7 Kelvin. Thats the cosmic background radiation.

Can you think of a device that converts electrical energy into heat?

An electric heater is an electrical appliance that converts electrical energy into heat. The heating element inside every electric heater is simply an electrical resistor, and works on the principle of Joule heating: an electric current through a resistor converts electrical energy into heat energy.
