Flashlight by light, battery, circuit, a hood and a reflective cup, circuit storehouse, switch, etc, the basic principle is the current from the battery, and then to the circuit, after adjusting circuit voltage and current, and then output to the light source for lighting.
The hypothesis for making your own flashlight could be: "If I connect the wires to the battery and light bulb properly, then the bulb will produce light when the circuit is completed." This hypothesis predicts that by assembling the components correctly, the flashlight will work as intended.
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.
Shake flashlights work by converting mechanical energy from shaking into electrical energy. Inside the flashlight, there is a magnet that moves back and forth when the flashlight is shaken. This movement induces a current in a coil of wire, which generates electricity to power the light. This process eliminates the need for batteries or electricity to operate the flashlight.
A torch, or flashlight, typically uses a battery to power the lightbulb. When the battery is inserted into the torch, it completes a circuit allowing the current to flow from the battery to the lightbulb, which then emits light. The chemicals inside the battery convert chemical energy into electrical energy, powering the lightbulb.
A shake flashlight works by using a magnet and a coil of wire to generate electricity through electromagnetic induction. When the flashlight is shaken, the magnet moves back and forth inside the coil, creating a changing magnetic field. This induces an electric current in the wire, which is then stored in a capacitor or rechargeable battery to power the flashlight's LED light.
A dynamo flashlight works by producing its own electricity. The flashlight has a crank that is turned by the operator. The crank runs a small generator inside that produces enough electric to run the flashlight.
If you put both batteries in backward in a two-cell flashlight, the flashlight is unlikely to turn on. This is because the voltage polarity would be reversed, which can prevent the circuit from functioning properly. It can also potentially damage the electronic components of the flashlight if left in that state for an extended period of time.

A source of electricity
Nope... if the circuit has a gap in it - the path of electrons is interrupted, and that would stop the circuit from working.
in a series circuit or it will not work. Put it after the bulb

The switch needs to be in the "on" position for the circuit to work, allowing the flow of electricity through the circuit. In the "off" position, the switch breaks the circuit, stopping the flow of electricity.
