  The present study looks into the pinch-off dynamics of a compound droplet,
which is suspended in another fluid in a parallel plate microchannel. The
droplet is subjected to a transverse electric field in the presence of an
imposed pressure driven flow. For the present study, a leaky dielectric model
have been taken into consideration. When a concentric compound droplet migrates
in a pressure driven flow, the inner droplet shifts from the concentric
position and forms a eccentric configuration that finally leads to the rupture
of the outer shell. The present investigation have uncovered that the temporal
evolution of droplet eccentricity as well as the kinetics of the thinning of
the outer droplet are markedly influenced by the strength of the electric field
as well as the electric properties of the system. The present study also shows
that the conversion of different modes of droplet pinch-off mode , such as the
equatorial cap breaking-off or the hole-puncturing mode can be attained by
altering the electric field strength and its electrical properties. Finally the
present study depicts that these factors also alter the pinch-off time as well
as its location on the outer interface. Therefore the outcomes of the present
study offers an effective means of modulating the morphology of compound
droplets in a confined channel by applying an electric field.
