What type of a circuit do flashlights use?
A flashlight is a series circuit. The batteries positive end connects to the flashlights switch. The switch connects to the center pin of the light bulb. The bulb filament is connected to the center pin of the bulb and the outer metal shell of the bulb socket. The shell of the bulb socket is connected to the metal flashlight's body which returns to the negative end of the battery. Turn on the switch and you have light.
The negative pole in a flashlight battery?
the negative pole of cylindrical batteries is the smooth end.
Does it matter which way the battery is places in the tube of a homemade flashlight?
Yes, it matters. Placing the battery in the correct position ensures that the electrical circuit is completed and the flashlight can function properly. Typically, the positive end of the battery should be facing towards the bulb or LED.
What type of metal can dig into a tree?
the type of metal on the end of an axe
What are everyday uses of series circuits?
Your battery-powered flashlight is a good example of a DC series circuit. Battery power is DC. The battery is connected to a wire or piece of metal that's connected to a switch that is connected to an incandescent light bulb (resistor/thermistor) which is then connected to another piece of metal or wire which is connected to usually a spring in the end of the flashlight which creates a ground to the negative terminal of the battery.
Where can you find a how to on building a VERY powerful electromagnet with any normal battery?
You coil wire around something round 100+ times, then stick one end of the wire on the + of the battery and the other end on the - of the battery. Start attracting metal!
How can you charge your phone battery if you dont have a charger?
I had to make a phone call from my car and the Cell phone battery went dead . I had a cigarette lighter variable charger cable and set it on 3 volts. Then I stuck a pin in the positive side hole of the cable end . I took the battery out found the positive and touched it with the positive Pin I had stuck in the cigarette lighter positive cable end hole I took another wire connected it to the outer end of the metal cable end and touched the negative of the battery just enough to make a phone call . You can also charge a cell phone battery with two 1.5 volt flashlight batteries in series ,a couple wires and scotch , tape .if you understand polarities
What is an complete circuit?
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.
If you took a laptop fan out of a laptop is there any way you can make it spin with a battery?
It might work using a single cell, like a flashlight cell, or you may have to connect several together, end to end. If it says on the fan case that it is 12v, that is 12 volts, and it should run on a regular 9-volt battery.
What is the proper battery cable connection when jumping two automotive batteries?
When jumping two automotive batteries, connect the positive () cable to the positive terminal of the dead battery and the other end to the positive terminal of the live battery. Then, connect the negative (-) cable to the negative terminal of the live battery and the other end to a metal surface on the car with the dead battery, away from the battery.
When does chemical change happen on a flashlight to produce electricity?
It happens when you turn on the flashlight and a circuit is created through the batteries, through the light filament, back down the outside of the batteries to the end of the batteries, etc. Switching off the flashlight breaks the circuit, curtails the chemical reaction in the batteries, and the light goes out.
How can I jump start my automobile battery?
Connect the red cable to the dead battery's positive post and then connect the other end of the red cable to the good battery's postive post. Then connect one end of the black cable to the negative post of the good battery and the other end to a piece of unpainted metal in the engine compartment of the dead battery's car. Then wait 2-3 minutes and try to start the car.
