30341-2. The erythrocyte sedimentation rate ( ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation . To perform the test, anticoagulated blood is traditionally placed in an ...
ESR Group. ESR Group Limited (ESR) is an Asia focused Real Estate services and investment company. It focuses on building and managing logistics properties such as warehouses and distribution centers. It is incorporated in the Cayman Islands but headquartered and listed in Hong Kong . Due to its acquisition of ARA Asset Management in 2022, ESR ...
Equivalent series resistance. Capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance. However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series ...
Electron paramagnetic resonance ( EPR) or electron spin resonance ( ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei.
An ESR meter is a two-terminal electronic measuring instrument designed and used primarily to measure the equivalent series resistance (ESR) of real capacitors; usually without the need to disconnect the capacitor from the circuit it is connected to. Other types of meters used for routine servicing, including normal capacitance meters, cannot ...

Internal resistance. Internal resistance model of a source of voltage, where ε is the electromotive force of the source, R is the load resistance, V is the voltage drop across the load, I is the current delivered by the source, and r is the internal resistance. In electrical engineering, a practical electric power source which is a linear ...
Dissipation factor. In physics, the dissipation factor (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of quality factor, which represents the "quality" or durability of oscillation.
