The Polynesian rat, or Pacific rat (Rattus exulans), known to the MÄori as kiore, is the third most widespread species of rat in the world behind the brown rat and black rat.he Polynesian rat is similar in appearance to other rats, such as the black rat and the brown rat. It has large, round ears, a pointed snout, black/brown hair with a lighter belly, and comparatively small feet.
Answers.comÂ® is making the world better one answer at a time. Power stage designer tool helps design the power stage of the most commonly used switch mode power supplies. It is also a great assistance for getting a deeper understanding of voltages and current flows inside converters.
While the previous gain stages are voltage amplifiers the power tubes amplify power, meaning voltage and current. The schematic doesn't show power tube grid voltage so we'll ignore the signal loss caused by the 220k grid leak resistors and assume 23 VAC on the power tube grid for a 14.6 gain to 174 VAC.
