my science teacher showed us a diagram of a tiny light bulb on top of a D-cell battery,there was an electric wire touching the bottom of the light bulb.the electric wire was touching the bottom of the light bulb to the bottom of the battery.BUT, the other end of the electric wire wasn't touching the tip of the wire, it was touching the side of the wire.

The question was that do you think the light bulb will light up?

I said no. I know why its no, but I don't know how to explain it. I need at least 3 examples why I picked"no."

If there was insulation (look that word up), you are correct. If there was bare wire without insulation, you are wrong. Why?

you don't make sense

1. The light bulb needs both sides of the battery
2. Only one side of the battery is being touched by the wire
3. The second wire is touching rubber not metal

one kilogram is equal to
