A simple way to reduce the loading error, without requiring a measuring device with higher input resistance, is to place a resistor equal to ** Rm **on the top side of the potentiometer, as shown in Figure 3.7 [21. The measured voltage is then

Thus the effect of the added resistor is to force *Vm *= *V/2 *at the central position (x = *0.5), *setting the error at that point equal to zero. The general equation for the absolute error is now

Equation (3.13) shows the dependence of the maximal relative error on *k. *Because in (3.10) x and 1 — x can be interchanged with no effect, we conclude that the relative error is symm...

Figure 3.4 is variation of the measured voltage of a potentiometer as a function of wiper position, for different values for *k. *This means that the input resistance of the voltage measurin...

Figure 3.3a shows the simplest signal conditioning for a potentiometer having a nominal resistance *R. *The linear or rotary movement from the device to be mea...

To obtain this expression, we did not use any mathematical model for *RT. *Thus this method can also be applied to PTC thermistors and other nonlinear resistive sensors.

In most applications NTC thermistors must be analyzed in the complete circuit where they are used. But in some cases they can be used as linearized sensors by shunting them with a resistor R. In th...

The circuit in Figure 2. 17a is suitable for measuring a temperature over a limited range, for example, that of cooling water in cars. It consists of a...

As the fastest growing demand of circuit and wiring diagram for automotive and electronics on internet based on different uses such as electronic hobbyists, students, technicians and engineers than we decided to provide free circuit and wiring diagram base on your needed.

To find circuit and wiring diagram now a day its easy. E-learning through internet as a right place to search an exact circuit and wiring diagram of your choice and it's much fun and knowledgable. On internet you will find thousands of electronic circuit diagrams some are very good designed and some are not. So you have to modify them to make them according to your needs but some circuits are ready to make and require no changes.

There are many categories of circuit and wiring diagrams like automotive, audio circuits, radio & RF circuits, power supply circuits, light circuits, telephone circuits, timer circuits, battery charger circuits etc. There are many types of circuit and wiring diagrams some are very easy to build and some are very complicated, some are so small and some contain huge list of parts.

We provides free best quality and good designed schematic diagrams our diagrams are free to use for all electronic hobbyists, students, technicians and engineers. We also provides a full educational system to students new to electronics.
