if you were correct it would be impossible for a resonant circuit to work…
if you connect to a battery a capacitor a diode and a coil in series the capacitor get charged to twice the battery voltage… thats because initially the capacitor can't change voltage instantly and the coil can so it start a current flow and when the capacitor reach the battery voltage the current keeps the same direction in the coil but the voltage reverts summing with the battery voltage to charge the capacitor to twice battery voltage…
