Ammeter current to be measured deflects the moving magnet. Since the ammeter shunt has a very low resistance, mistakenly wiring the ammeter in parallel with a voltage source will cause a short circuit, at best blowing a fuse, possibly damaging the instrument and wiring, and exposing an observer to injury. In AC circuits, a current transformer converts the magnetic field around a conductor into a small AC current, typically either or at full rated current, that can be easily read by a meter. In a similar way, accurate AC/DC non-contact ammeters have been constructed using Hall effect magnetic field sensors. A
Electrical engineering technology degree and considered craftsman technicians. Eventually, with additional experience and certifications obtained then the craftsman technicians may advance to master craftsman technicians. Electrical/electronic engineering technologists are broad specialists, rather than central technicians. EETs have a bachelor's degree and are considered applied electrical or electronic engineers because they have electrical engineering concepts to use in their work. Entry-level jobs in electrical or electronics engineering generally require a bachelor's degree in electrical engineering, electronics engineering, or electrical engineering technology. Electrical engineering technology Electrical/Electronics engineering technology (EET) is an engineering technology field that implements and applies the principles of electrical engineering.
