Ammeter permanent magnet causes the coil to move. The modern form of this instrument was developed by Edward Weston, and uses two spiral springs to provide the restoring force. The uniform air gap between the iron core and the permanent magnet poles make the deflection of the meter linearly proportional to current. These meters have linear scales. Basic meter movements can have full-scale deflection for currents from about 25 microamperes to 10 milliamperes. Because the magnetic field is polarised, the meter needle acts in opposite directions for each direction of current. A DC ammeter is thus sensitive to which way round
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.
