If you place an end of a wire on the negative or positive side, put the outer metal part of the light bulb's cap on the other, and place the other end of the wire on the light bulb's cap's inner metal part, it will turn on.
Tip
Before you try to do this, always check that the voltage of the battery is equal to, or a bit less than, the voltage of the light bulb!
Otherwise the light bulb may only give out a very bright flash and could easily be destroyed.
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.
If you join the glass of a light bulb to the battery to complete a circuit, the light bulb will not light up. The glass is an insulator and does not conduct electricity, so the current will not flow through the bulb to produce light. It's important to use the metal contacts of the light bulb to connect the circuit for it to work properly.
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.
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.
The first flashlight, invented in the 1890s by Conrad Hubert, used a dry cell battery to power an incandescent light bulb. The battery provided electricity to the filament in the bulb, causing it to glow and produce light. The design was simple and required the user to press a switch to complete the circuit and illuminate the bulb.
The battery chemically stores electricity so when you 'switch on' the light then electricity flows from the battery to the bulb. The bulb the heats up to glow white and the reflector shines the light out of the battery powered light

Take a battery, a wire and a little light bulb. Put the wire on the flat part of the battery then put the other end of the wire on the side part of the bottom of the light bulb. Put the end of the light bulb on the top of the battery, dont touch the wire to the top when the light bulb is on it because is either shocks you or doesnt work.

The citric acid inside in a fruit could make it work. Fruits that is part of the citrus family has a contains a citric acid. For example a lemon, it could make a light bulb work. :)
You need: two pieces of wire, a battery, an electric light bulb to work on the same voltage as the battery and a bulb holder that fits the bulb.Connect one wire to the positive post of the battery and the other end of this wire to one of the terminals on the bulb holder.Connect the other wire to the negative post of the battery and the other end to the other terminal of the bulb holder. Screw the bulb into the holder and the bulb should light up.Another answerThere are many different types of light bulbs. Some, such as automobile lights and solar garden lights, were designed for use with batteries.Ordinary light bulbs have an electric wire that glows brightly when the right voltage is applied. These will work with either direct current from batteries or alternating current from a power line or generator, but the amount of voltage must be correct for the specific light bulb or, if the voltage is too low, it will not illuminate properly. If the voltage is too high the light bulb will be destroyed.Fluorescent light bulbs normally work from alternating current, but a direct current adapter called a DC inverter can be used to change battery power to alternating current.
To build the light bulb.
Using a remote control similar to those ones used to turn on electronic devices. The infrared rays can switch the light bulb on, since it has a small transistorised circuit that can actuate a tiny relay to put the light bulb in series with the electric circuit.
no
im not sure if this will work or not but... If you use a 9v battery threw an inverter, then a step-up transformer to convert 9v DC to 120v ac i think it will light the bulb, however current decreases when you do that and i dont know how much a light bulb needs..worth a try, i might actually try it now
