Manga Guide 3 (pp90 – 116)
1.
What
is the relationship between heat and electricity? Please provide a metaphor.
When electricity flows through a resistance
heat is produced. The heat produced in this way is called joules heat. I would
look at like this if you have this metaphorical friction that happens when
electricity goes through a resistance then you have heat being given off just
like when squeeze something from a tube.
2.
Why
is it warm near an incandescent light bulb?
Its warm around a light bulb because of the
thermal energy that is emitted from the object from the resistance of energy
going though it that heats up the object (the light bulb). These are called
thermal emissions.
3.
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?
A superconductor is a material that has no
electrical resistance. It has a near
perfect ability to conduct electricity. This means a metal that is
superconductor would have a floe of electricity within it that would never
degrade the material. Tin is an example
of a metal that is a superconductor. It is a type 1 superconductor with a
critical temperature of -269degrees Celsius and -457degrees Fahrenheit.
To make a metal a superconductor it would
need to be cooled down past a certain critical temperature.
4.
What
is Ampere's Law?
Ampere’s law Is the creation of circular
magnetic fields around a wire when an electric current flows through it.
5.
If
current of the same size flows in the same direction in two electric wires
placed side by side, what happens?
Is this happens then the two electric
magnetic fields generated by the two wire will combine to create one larger
magnetic field and will result in the to wires to attract one another.
6.
What
happens if current of the same size flows in opposite directions in two
electric wires placed side by side?
Then the opposite thing will happen and the
two magnetic fields retract each other.
