Charles Proteus Steinmetz (April 9, 1865 – October 26, 1923) was a German-born American mathematician and electrical engineer and professor at Union College. Among other great achievements, he fostered the development of alternating current and made ground-breaking discoveries in the understanding of hysteresis (Steinmetz Equation). He developed the use of complex number phasor representation in electrical engineering, whereby the analysis of electrical networks at steady state can be carries out by algebraic equations without the need to apply differential equations. He was apparently not only a genius but also a remarkable human being.
The expression of ceramic capacitors losses by a parallel resistor (presented in the video linked here) fits unbelievable to what Steinmetz predicted about a 100 years ago.

7 年Hi David, I am afraid I don't follow you. Can you elaborate please?

7 年The caps are underestimated. Good cap makes significant difference at low power and high power, as well. E.g. 900MHz 100W, you can warm up your coffee on standard caps and trimmer caps.
