What happens if current of the same size flows in opposite directions in two electric wires placed side by side? What is the relationship between heat and electricity. Please provide a metaphor.
Heat is the vibrations of atoms and molecules. When you touch a metalic object, the heat in your hand causes the atoms in the object to vibrate faster. The vibrations can move very quickly from atom to atom, so the heat gets carried away from the point of contact. That's what makes it feel cold. Like when I pet (current) my dog and she sheds (heat) everywhere.
Why is it warm near an incandescent light bulb?
because of thermal emission, when the temperature of a substance increases and thermal energy is emitted as electromagnetic waves
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 material that can conduct electricity or transport electrons with no resistance.
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.
If current of the same size flows in the same direction in two electric wires placed side by side, what happens?
If two parallel wires have currents traveling in the same direction, the magnetic fields generated by those currents between the wires will both point in opposite directions resulting in the wires attracting each other.
What happens if current of the same size flows in opposite directions in two electric wires placed side by side?
a force of repulsion is generated between the wires
