The standard work covers all the fundamentals of mathematics and electrical engineering needed to prepare for the master examination in electrical professions. As a valuable reference work, it equally supports practitioners in their daily tasks. Specifically, in the mathematical area: general calculations, coordinate systems, technical calculations. In terms of subject matter: physics, chemistry, electrochemistry, electrical resistance and circuits, work/power/energy, electric fields and capacitors, magnetic fields, alternating current technology, three-phase alternating current/three-phase current, and the basics of power calculation.
