What are the values of
and
in the capacitance equation?
For a current coming into the inductor the magnetic field is circular, but in the inductor solenoid, the current is circular. So the induced
field is either up or down [along the inductor]). So how exactly can the inductor resist the change?
How do inductors store and discharge energy?
I remember that capacitors in series combine similarly to resistors in parallel, but how do inductors combine?
How does energy get transferred from the inductor to capacitor in the LC circuit?
If energy sloshes back and forth between the capacitor and inductor, does this mean that current never goes past the inductor?
In a mechanical oscillator there can be different forces (air resistance, friction, etc.) that keep the system from being ideal as we discussed with drag. Are there other factors besides resistance that would stop an LC circuit from being ideal? (How do they lose energy?)
For the LRC loop rule, why is the
term negative?
You mentioned there is a mechanical analogy to resonance- does that mean that inductors have a resonant frequency that is a property of the material?
