Electronic current transformers include Hall current sensors, Rogowski current sensors, and AnyWay variable frequency power sensors (which can be used for voltage, current and power measurement) dedicated to variable frequency power measurement. Compared with electromagnetic current sensors, electronic current...
Nowadays, the “Eratosthenes experiment” is run every year on the March equinox, in which schools at the same longitude are paired up to measure the elevation of the Sun at the same point in time, in order to obtain a measurement of the circumference of the Earth. (The equinox is more...
There is a huge variation in fields of applications for resistors; from precision components in digital electronics to measurement devices for physical quantities. A few popular uses are described below. Resistors in series and parallel In electronic circuits, resistors are very often connected in seri...
Conductive carbon blackis a filler commonly used to create electrical conductivity. The fine black powder is added at relatively high levels and creates only black-colored parts. Some types of carbon black may slough, or shed, invisible dust. For most applications, this is not a problem; but ...
Here is a typical size listening room where a measurement mic has been placed at the listening position and the loudspeaker has been moved to three different locations within a two foot radius: As one can see, below the room’s transition frequency of about 300 Hz in this example, the bass...
Q. Is Ra & RMS exclusively used for measuring surface quality on metal finishes? Is there another measurement value used for measuring Roughness Average on glass mirror surface? How does Ra of metal surface compares to surface of a glass mirror?
to a range of actuators with different sizes, resulting in the production of high-performance VCAs measuring 12‒65 mm in diameter and 12‒75 mm in length (at mid-stroke) and are suitable for various applications, such as semiconductor, military, space, and test and measurement. (Figure ...
