ExploringCurrent sensor voltageBefore, we need to define what is current correctly? As mentioned above, current is the strength or flow rate of an electric charge. In a DC system, current flows in one direction, known as' unidirectional '. The common sources of direct current include batteries and solar cells. That means there are two situations: AC to DC current, AC to DC current. In an AC system, the current reverses direction at a given frequency. In our businesses and homes, we have AC power sources based on 50 or 60Hz (depending on your country). This type of alternating current is usually sinusoidal (such as in the shape of a sine wave). The most typical AC power source is the local power plant. The current generated by photovoltaic cells is direct current, which must be converted into alternating current to supply power to our homes. UPS (or computer battery backup system) is the same - energy is stored in batteries and must be converted to AC power to provide household electricity.

万彩网100线路The term 'current' is defined as ampere in the International System of Units (SI), which must be kept in mind before discussing the voltage of current sensors. It is usually abbreviated as' ampere 'and written with the symbol A. Current is usually written with the letter I, which can be traced back to the French phrase intensity é de courant ("current intensity" in English). A and I are both acceptable abbreviations for current. ADC is usually abbreviated as' current 'and' DC 'respectively. One ampere is equal to one Coulomb charge passing through a given location in one second (one Coulomb contains approximately 6.242 × 1018 electrons). Electric current always generates a magnetic field. The stronger the current, the stronger the magnetic field. By using various techniques to measure electric fields such as Hall effect, induction, or magnetic flux, we can measure the electron flow (current) in circuits.
