Current Sensing Techniques using Different Current Sensors Current is a very critical factor in Electronics or Electrical Engineering. In electronics, current can have a bandwidth from few nano-amperes to hundreds of amperes. This range can be much wider in Electrical domain typically to several thousand amperes, especially in Power Grids. There are different methods to sense and measure current inside a circuit or a conductor. In… |
