...inductor "stores" energy in an electromagnetic field

...capacitor "stores" energy in an electrostatic field.

...resistor does NOT "store" energy, it can only "dissipate" it.

...only AC-voltage can be "stepped-UP/DOWN"

...but, DC-voltage can be "converted" into AC-voltage (but always at a loss).
