I don't know about the OP, but I found your explanation very clear
and informative  :)

Excellent.

Perhaps you would like to take a crack at substituting
capacitance for inductance, current through  for voltage
across, and electric field for magnetic field to transform
it into a similar explanation of capacitance.

Er, I just got to the section in my book dealing with Kirchoff's Law.
 
All
I know - well, what *think* I know - about Capacitance is that it's a
measure of a material's ability to hold a build-up of electrons, and
that
,
if it is near enough to a conductor, the electrons will jump to that
conductor ("discharge"), so it can be used to either give a sudden
burst
of
power (which IIRC is used in camera flash units??) or, if the power
contiues flowing, to create "pulses" of power.  I don't know the
Math,
but
have in my Notebook that 1 Coulomb=1Ampere per 1 Second , and
Farads=coulombs divided by Volts.    ANd that the Watt rating indic
ates
when a Capacitor will fail, so always use a Watt rating at least 2
times what your circuit's normal operation will need, just in case of
a power surge.

I don't yet understand "electric field";  I haven't gotten that far
yet with my self-study.

Isn't "electric field" where sports teams from competing power
companies play against each other? ;)

Team NPN versus Team PNP...?
