Resistive divider

An a-Si H-based position sensor consists of an intrinsic film sandwiched between two transparent conductive electrodes [637]. Two line contacts on the top are perpendicular to two on the bottom. When a light spot is incident on the device, carriers are generated, and a photocurrent flows to the contacts. The contacts form resistive dividers, so that from the ratio of the photocurrents the lateral position relative to the top or bottom contacts can be determined. The top contacts give the x-position, and the bottom contacts the y-position. 

The increase in temperature is then the rise in resistance divided by the change in resistance increase per degree centigrade. 

The inverse of the conductivity of each reaction is its resistivity, and the sum of all the resistivities divided by their number gives the average resistivity, RF, of the reaction,... 

Experimentally it was found that at constant temperature the increase in the thermal resistance caused by deformation or formation of mixed crystals static disturbances of the lattice) is to a remarkable degree of accuracy proportional to the increase of the electrical resistance divided by the absolute temperature. If we compare the above formula with the Wiedemann-Franz-Lorenz law for pure metals,... 

Rwao being the total resistance. Dividing by Aw and noting Eb = c/T4, A = rfr2, and Aw = 2rrrK , thus AlfAm = r /2, and the heat flux to ambient is... 

I he parallel resistance is just the prodiici ol the two resistances divided by the sum. 

Each sensor element changes its electrical resistance (Rmax) when exposed to volatile compounds. In order to produce consistent data for the classification, the sensor response is presented with a volatile chemical relative to the baseline electrical resistance in fresh air, which is the maximum change in the sensor electrical resistance divided by the initial... 

What is the voltage at each lightbulb Remember that a series circuit has voltage drop. (Hint Because the lightbulbs have equal resistance, divide the total voltage by the number of lightbulbs.)... 

A bulk property of a material is one that is independent of the dimensions of the sample. When the length and width of the sample are much greater than the thickness, a more convenient unit to use is the sheet resistance, which is equal to the bulk resistivity divided by the thickness. 

DAs use transformer and active balanced inputs. Active balanced outputs may use one of two basic approaches a resistive divider network or individual driver ampHfiers. Figure 16.36 shows the resistive...
