How to Help Your 6th Grader Learn New Math Terms. There tends to be a shift in the focus of math curricula from 5th grade to 6th grade. In 6th grade, students are introduced to new concepts, including ratios, proportions and statistics. Similarly, they begin to learn algebraic expressions like solving for a variable and exponents.
A flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer. It was initially designed to generate high voltage sawtooth signals at a relatively high frequency.he flyback transformer is used in the operation of CRT-display devices such as television sets and CRT computer monitors.
The reason it is called a flyback transformer is because the primary winding uses a relatively low-voltage saw-tooth wave. The wave gets strengthened first and then gets switched off abruptly; this causes the beam to fly back from right to left on the display.1  Cathode ray tube. 2  Televisions.3  Plasma Lamps.he reason it is called a flyback transformer is because the primary winding uses a relatively low-voltage saw-tooth wave.
