... At the temperature room, at any instant, a number of free electrons that are unattached to any atom drift randomly throughout the material. This condition occurs when no voltage is applied across a piece of intrinsic Si (as illustrated in Fig. 12). When a voltage is applied across the piece of intri ...

S2014, BME 101L: Applied Circuits Lab 5a Characterizing
... Note: that the data sheet gives two different values in ohms: the impedance (actually, the magnitude of the impedance) and the DC resistance. In this lab you will measure both. The impedance is not really a single number though, but a function of frequency, and you will model the impedance of the lo ...

... The direction of the induced current is determined by the left-hand rule for electron flow. If the fingers coil around the direction of electron shown, under and over the winding, the thumb will point to the left for the north pole.

3.5.4 Swain Meters - Cathodic Protection Co Ltd
... The 700 mA Tester N-10 drives 70 milliamperes direct current regulated to within ± 1 mA into a 10 turn loop which is 4 1⁄2" in diameter. The leads are 3" long, so the 70 mA is also available. It is intended to ensure the Swain Meter is functioning properly. The 70 mA current flows in the wire to the ...
