Since the switch is open, no current flows in the circuit (i=0) and vR=0. Recall that in resonance, the voltage across the reactive elements is Q times larger than the voltage on the load! In essence, that is enough to perform the impedance transformation. When a series connection of a resistor and an inductor—an RL circuit—is connected to a voltage source, the time variation of the current is (turning on), where the initial current is ; The characteristic time constant is where L is the inductance and R is the resistance.
