Learn MoreConsidering the graphs of power vs time in capacitor/inductor only circuits, the average power is 0. Shouldn''t this mean that on average reactive power is just 0? No, it doesn''t mean that. Reactive power isn''t the average of the instantaneous reactive power; the absolute value of reactive power is the amplitude of that oscillation of energy.

Learn MoreThe above image shows a Mylar film capacitor. The top "683" marking indicates the capacitance value, which is 68,000 picofarads (pF). To get this value, you multiply the leading digits (68 in this case) by 10 raised to the power of the last digit (3), and the result is the capacitance in picofarads (in this case, we get 68×10 3 pF). There are …
