Which item would allow the bulb to light up if it were used to connect point A and point B?
The purpose of the copper wire is to _______________. A magnet and a metal paper clip have a stronger magnetic attraction when the distance between them is _____________. Which position on the bar magnet would have the strongest attraction to the north pole of another bar magnet? Predict the motion of magnet X.
Which item would allow the bulb to light up?
battery
A battery provides the energy of motion needed to make a light bulb glow. The energy released by chemical reactions within the battery is transferred to the light bulb as energy of motion carried by electrons. In the battery, chemical energy is stored in the bonds between the atoms of certain chemicals.
What do you need to do to light up a bulb?
Light the bulb using two wires. Attach one wire to the negative end of the battery and wrap the other end of the same wire around the base of the bulb. Attach the other wire to the positive end of the battery with electrical tape and to the base of the bulb, completing the circuit and lighting the bulb.
Why does the bulb light up when the needle touches a paper clip?
10. 11. The diagram below shows a game where players try to move a metal needle through three metal paper clips without letting the needle touch the clips. A bulb lights when the needle touches a paper clip, signaling that the player has lost.
What do the objects that light up the bulb have in common?
What do the objects that lit up the bulb have in common? All the objects that lit up the bulb are made of metallic materials. The lead core of a pencil (graphite) also conducts electricity. Some metals are better conductors than others.
Is a light bulb an insulator?
A bulb is made out of conductors as well as insulators. The filament, a thin tungsten wire in the light bulb, conducts electricity. Two wires that connect the supply to the mains are also conductors. The bulb’s glass cover, the support inside the bulb and the cover of the socket are insulators.
When did the bulb light up?
Incandescent Bulbs Light the Way Long before Thomas Edison patented — first in 1879 and then a year later in 1880 — and began commercializing his incandescent light bulb, British inventors were demonstrating that electric light was possible with the arc lamp.
What do the objects that did not light up the bulb have in common?
Bulb does not light up Some metals are better conductors than others. What do all the objects that did not light up the bulb have in common? Some metals are better conductors than others. If the bulb does not light up with some metallic objects, it might be that the current is very small.
