Terminology In Electrical Measurements

Measurement is the process to obtain information specific physical quantities, such as voltage (V), electric current (I), the resistance (R), conductivity (ρ), and others. The data obtained can be a value in the form of numbers (quantitative) or in the form of a statement is a statement or generalization (qualitative). Information obtained in a measurement called the data. In accordance ...

Electron Transmitter Oscilloscope

Electron transmitter is the most important part of an oscilloscope. Cathode in the CRT (Cathode Ray Tube) will emit electrons to electrodes CRTmelalui screen pemfokus electron beam intensity is determined by the number of electrons emitted by the cathode. Light-reflecting material on the CRT screen can be obtained from sulphide, oxide atausilikat of cadmium, which is activated by additional material ...

Accuracy and Precision

Accuracy stated conformance level measurement results to the price or the actual value; moderate accuracy states the degree of similarity in a group of measurement or number of instruments. Suppose we compare two voltmeter with models and from the same manufacturer. It should be the second voltmeter can be read with the same accuracy, but can also occur both the ...

Depositary Electric Current

Electric current can be generated through the movement of electrons due to a chemical process. A battery or accumulator produces electron flow continuously through the chemical reaction between the two electrodes of different kinds. Electrode is a solid conductor in which an electrical current can flow through it. One electron collecting electrode and the other electrode gives electrons. Dry batteries ...
