2. Mathematics of three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Mathematics_of_three-phase...

   In electrical engineering, three-phase electric power systems have at least three conductors carrying alternating voltages that are offset in time by one-third of the period. A three-phase system may be arranged in delta (∆) or star (Y) (also denoted as wye in some areas, as symbolically it is similar to the letter 'Y').

3. Kirchhoff's circuit laws - Wikipedia

   en.wikipedia.org/wiki/Kirchhoff's_circuit_laws

   The current entering any junction is equal to the current leaving that junction. i 2 + i 3 = i 1 + i 4. This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or equivalently:

4. Leading and lagging current - Wikipedia

   en.wikipedia.org/wiki/Leading_and_Lagging_Current

   Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...

5. Capability curve - Wikipedia

   en.wikipedia.org/wiki/Capability_curve

   Capability curve of an electrical generator describes the limits of the active and reactive power that the generator can provide. The curve represents a boundary of all operating points in the MW/MVAr plane; it is typically drawn with the real power on the horizontal axis, and, for the synchronous generator , resembles a letter D in shape, thus ...

6. Form factor (electronics) - Wikipedia

   en.wikipedia.org/wiki/Form_factor_(electronics)

   In electronics and electrical engineering, the form factor of an alternating current waveform (signal) is the ratio of the RMS (root mean square) value to the average value (mathematical mean of absolute values of all points on the waveform). [1] It identifies the ratio of the direct current of equal power relative to the given alternating ...

9. Ohm's law - Wikipedia

   en.wikipedia.org/wiki/Ohm's_law

   Ohm's law, in the form above, is an extremely useful equation in the field of electrical/electronic engineering because it describes how voltage, current and resistance are interrelated on a "macroscopic" level, that is, commonly, as circuit elements in an electrical circuit.
