Q1:

Consider a parallel plate capacitor being charged. Identify the incorrect statements

A Energy stored in the capacitor does not enter it through the connecting wires but through the space around the wires and plates uf capacitor

B Rate at which energy flows into this volume is equal to the integration of the Poynting vector over the boundary of the volume between the plates.

C The Poynting vector points everywhere radially outward of the volume between the plates

D The Poynting vector points everywhere radially into the volume between the plates

ANS:D - The Poynting vector points everywhere radially into the volume between the plates

In a parallel plate capacitor, current passes through the connectors. is the Poynting vector which points radially into the volume.
