What is the relationship between heat and electricity. Please provide a metaphor.
Heat is the vibration of molecules. As current is passed through a conductor the electrons bump into the molecules/atoms, which in turn increases vibration and raises heat. One could think of the haunted houses at Halloween Horror Nights with people (electrons) moving through the house (conductor) bumping into the walls and objects inside.
Why is it warm near an incandescent light bulb?
Light bulbs work by thermal energy being emitted via electromagnetic waves, which once the temperature gets to a certain point visible light from the visible light portion of the spectrum is emitted. Because the production is paired with thermal energy, light bulbs exude heat.
What is a superconductor? What are they used for in real life? You may have to look this up. How could one make a metal a superconductor?
Materials typically made of metal wherein they are put into an environment near absolute zero. This causes the atoms within the substance to almost stop moving allowing electrons to pass through with as little resistance as possible. They're used in things like particle accelerators and in magnet separation (which is totally nuts) in making pigments. You can make a metal superconductor by somehow bringing a metallic material (I would assume you could use some sort of a wire?) to near absolute zero.
What is Ampere's Law?
"Ampere's Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop."
An example is sending current through a wire to create a circular magnetic field.

If current of the same size flows in the same direction in two electric wires placed side by side, what happens?
The strength of the current is now twice the original.
What happens if current of the same size flows in opposite directions in two electric wires placed side by side?
Both fields created repulse one another and are negated.
