Student: I can't figure out how to do that, since I can't seem to cut off more than two of the four corners. Mentor: Don't worry, what I asked you to do is actually impossible! There are only six faces on a cube, so the highest number of sides possible is six. Student: That makes sense. I bet you can do that with any prism-it's just a matter of angling the cross section correctly to intersect all of the faces. Mentor: You're very right, any prism can be cut in such a way that the cross section has as many sides as the prism has faces. However, not all shapes have this same property.
A variable frequency transformer including: a first parallel circuit including at least two of the rotary transformers arranged in parallel and having an isolating circuit breaker connected to a rotor winding of each of the rotary transformers, and a separate synchronizing circuit breaker connected to a stator winding in each of the rotary ...
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. You'll see transformers at the top of utility poles and even changing the voltage in a toy train set. Basically, a transformer changes electricity from high to low voltage using two properties of electricity.In an electric circuit, there is magnetism around it.his lower voltage electricity is put into the local electric wires at a substation. The substation breaks the larger amount of power down into smaller pieces at lower voltage. It then is stepped down again and again. Once smaller transformers take that voltage down to usually 7,200, the power leaves this substation.
