The dependence of the current on the temperature
A bridge circuit is often used, in which three further reference resistors are used in addition to the measuring resistor - do my homework website . Thermistors show a clear difference in their resistance behaviour even with relatively small temperature changes.
The dependence of the current on the temperature at constant voltage. However, in the case of thermistors (PTC thermistors, hot conductors), the temperatures are not directly proportional to the resistance. On the one hand, one can therefore do without complicated measuring circuits - - a simple ammeter is often sufficient - on the other hand, the conversion of current strengths into temperature values is somewhat more difficult.
Regardless of which resistors and which measuring principle are used, the following applies: The actual measuring part has a relatively small volume and is free of external insulation, so that a fast temperature equalisation with the substance to be measured is achieved - do my engineering assignment . In this context, one often speaks of temperature sensors.
Accumulators (batteries) are rechargeable electrical sources. Electrical energy is stored in them. As voltage sources, they provide the drive in electrical circuits. The mode of operation of accumulators is based on electrical conduction processes in liquids. The first form of an accumulator was built by Johann Wilhelm Ritter in 1803 in Jena. An accumulator consists of 6 identical cells connected together.
