Try it in Spice with realistic small resistances and inductance. Every electrical engineer is taught, in basic theory: The voltage on a capacitor cannot change instantaneously. The current in an inductor cannot change instantaneously. These become much clearer when you write down the INTEGRAL form of the V-I relations.
