Circle diagram Circle diagram First conceived by A. Heyland in 1894 and B.A. Behrend in 1895, the circle diagram is the graphical representation of the performance of the electrical machine drawn in terms of the locus of the machine's input voltage and current. The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors. The Heyland diagram is an approximate representation of circle diagram applied to induction motors, which assumes that stator input voltage, rotor resistance and rotor reactance are constant and stator resistance and core loss are zero. Another common circle diagram form is as described in the two
Brain Age: Train Your Brain in Minutes a Day! to 120 as fast as they can without slurring the names of numbers. Word Memory gives the player a list of 30 four-letter words.

Another puzzle called Connect Maze gives players a randomly created group of circles, with letters and numbers in them. There is one circle for every letter in "A" through "M", as well as a circle for every
