Cell for resistivity measurement of a strip or elastic fibre sample (E) using four electric wires (12) each having an end portion. The cell comprises a cylinder (24) and the wire ends are bent so as to each form a loop (44) about the cylinder, terminated by a hook (45) and having...
Show that the percentage error in the measurement of resistance by a metre bridge is minimum when the null point is near about the centre of the wire. View Solution If the error in the measurement of radius of circle is 3% then calculate the error in measurement of area of circle :- ...

Both meters are ideally suited for measuring contact resistance of relays, switches, and PCB traces, typically...
A brake force (attenuation force) of a magnetic damper 9 is proportional to a relative moving speed of a cylindrical member 6 and a square of an interlinking magnetic density and, inversely proportional to a resistivity of the member 6. Therefore, the magnetic damper is constituted of a ...
Measuring the resistivities of metal wires using a digital multimeter In a typical first-year undergraduate laboratory the resistivity of a metal is determined by measuring the resistance of a metal wire of known dimensions accurately, for example with a Wheatstone bridge. This procedure may be too...

The design of a hot wire anemometer presents an interesting application for operational amplifiers. The purpose of the instrument is to measure air speed by its cooling effect upon an electrically heated platinum filament that exhibits a high positive temperature coefficient of resistivity.

C Series Strain/Bridge Input Modules Modular hardware used in CompactDAQ and CompactRIO systems for dynamic signal acquisition of strain/bridge-based measurements.
A second step is to develop special materials parameters to reduce the ac losses of composite multifilamentary BSCCO-2223. Recent work has led to increased resistivity in the metal sheath, twisted and fine multifilament configurations, as well as underlying improvement of critical current density ...
