E=L*di/dt and i=C*dv/dt
Neither of those have a "resistance term" (ideal components), however, as mbarazeen points out, there are parasitic elements... capacitors have ESR (also ESL) and inductors have the resistance of the wire itself as well as inter-winding capacitance.
Much of our physical world is governed by differential equations which relate physical quantities and their derivatives. "Changing suddenly" is an imprecise way of saying tha some real physical quantity has an infinite derivative. Many relationships would become impossible to deal with if we allow things to go to infinity. My question is if you had access to an infinite quantity of voltage, current, charge, energy, or whatever. How would you handle it?Hi,
What this means on real?:
The voltage (current) of a cap (inductor) does not change suddenly??
P.s why they show an inductor by letter "L" and not "I"? what "L" letter Stands for?
