What caused the bulb to light up using battery?
This is because the electrons flow out of the negative terminal of your battery, through the bulb, and back into the positive side. This creates a circuit that causes the bulb to light up.
Can you light a lightbulb with a battery?
How can I power a lightbulb with a battery? A: Just connect the positive terminal of the battery with one electrical contact of your light bulb and the negative terminal with the other electrical contact of the bulb.
How do battery operated light bulbs work?
When you connect the two wires to the light bulb, it will light up [source: Dave]. Electrons flow out of the negative terminal of the battery, through the bulb and back into the positive side of the battery to make the bulb light up [source: Energy Kids].

When a bulb is lit Is there a flow from the battery to the bulb there is also an equal flow from the bulb back to the battery?
Student 1: “When the bulb is lit, there is a flow from the battery to the bulb. There is also an equal flow from the bulb back to the battery.” Student 2: “The Flow is only from the battery to the bulb.

You would need 10 12-Volt batteries to light it up if you insist on using a 120 Volt bulb. It’s easier to use a single 12 Volt battery and hook it up to a 12 Volt bulb. Most cars have an electrical system of 12 Volts.
Can you light a bulb with a battery and one wire?
One wire will go from the + side of the battery to one side of the light bulb, the other will go from the other side of the light bulb to the – terminal. Answer 2: The power for the light bulb does not come from the wire – it comes from the battery. The wire simply provides the conducting path.
Can LED lights run on battery?
The answer is “Yes”. A 12V strip can run on a power supply a little lower than its required electrical voltage, like a 9V alkaline battery. This setup is even entirely safe to operate. LEDs are not rated for 12 volts, at least not directly.
