When we discuss them with respect to the type of signal, we
can say "electrical" instruments deal with 'Analog' signals
mostly defined by the equations of classical physics. They
certainly obey Ohm's Law. Term 'Electrical' is associated
with the typical conception of Electric Field(E) which
exerts electric Force(F) on a charge particle(q) and it
produces electricity, Where F=qE.
But 'Electronic' instruments are made to deal
with 'Digital' signals. Analog electrical signal is changed
to Digital signals ( 0, 1). They are semiconductors devices
which never obey Ohm's Law and implemented with logic
gates.
