Can you light more than one lightbulb with only one battery?

Yes! Connect all the bulbs in parallel.. i.e. Battery positive terminal will be tied to one side terminals of bulb and other terminal to the other.

But it will result in less power delivered.. and fast battery usage.

This process will produce less than 1.5 volts DC (AA/AAA battery). However, producing 1.5 volts does not necessarily produce enough current to make the lamp actually power up to full use. Voltage is only the POTENTIAL to do work.

(See Ohm’s law: V = I x R) This kind of battery generally produces only a few milliamps. Even multiple potatoes may not generate enough amperage. Most assuredly, it will NOT power a household light, but a small flashlight lamp will GLOW.

Cut the potato in half. Wrap the end of a piece of wire around a galvanized nail and wrap the end of a second piece of wire around a penny.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
