The electric force is carried by elementary particles called electrons, protons and neutrons. Since the voltage drop across the resistor, V R is equal to I*R (Ohms Law), it will have the same exponential growth and shape as the current. The function of the inductor depends upon the frequency of the current passing through it. The inductive reactance of an inductor increases as the frequency across it increases therefore inductive reactance is proportional to frequency ( X L ) as the back emf generated in the inductor is equal to its inductance multiplied by the rate of change of current in the inductor. That is for higher frequency signals will be passed less easily and vice versa. The high value of current at resonance produces very high values of voltage across the inductor and capacitor. It is 18 square root. This reaches the V/R value and holds for the remainder of the pulse. Static resistance determines the power dissipation in an electrical component.
