In electronics, volumetric efficiency quantifies the performance of some electronic function per unit volume{{of what|reason=This explanation is completely ambiguous. As stated, it mixes time per unit with volume of…what?|date=May 2024}}, usually in as small a space as possible.  This is desirable since advanced designs need to cram increasing functionality into smaller packages, for example, maximizing the energy stored in a battery powering a cellphone.  Besides energy storage in batteries, the concept of volumetric efficiency appears in design and application of [[capacitor]]s, where the "CV product" is a [[figure of merit]] calculated by multiplying the capacitance (C) by the maximum voltage rating (V), divided by the volume. The concept of volumetric efficiency can be applied to any measurable electronic characteristic, including [[electrical resistance|resistance]], [[capacitance]], [[inductance]], [[voltage]], [[electric current|current]], [[energy storage]], etc.
