Yes - transformers have capacitance between their primary and

A miniscule amount, mayhap: 99.999% of the energy transferred is
transferred *inductively*, though (and 99.999% of the losses are
inductive, too ;-)
There is enough capacitative couling for better trasnformers to be wound
with an (earthed) screen winding between primary and secondary layers
to reduce the transfer of energy to approximately zero.
