elelectricity genrates heat bc the atoms that make up a substance are always vibrating. Temperature correspond to how fast atoms vibrate. Thus electrical wire is used to flow electrons bc it has little resistance making its temperature near a state of rest.
Why is it warm near an incandescent light bulb?
light emission due to thermal emission mostly ends up becoming 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?
superconductor is a material that has zero electrical resistance due to being below a critical temp (close to absolute zero)
They can be used in MRIs or particle accelerators. lower temperature.
What is Ampere's Law?
magnetic fields create a circular pattern around wire if you point your right thumb in direction of current your fingers curl in direction of magnetic field is generated
If current of the same size flows in the same direction in two electric wires placed side by side, what happens?
2 magnetic fields are combined to one big magnetic field, s force of attraction causes the the two wires to attract each other
What happens if current of the same size flows in opposite directions in two electric wires placed side by side?
force of repulsion causes two magnetic waves to negate each other
