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.
A transformer is a device with two or more magnetically coupled windings (or sections of a single winding). A time varying current in one coil (called the primary winding) generates a magnetic field which induces a voltage in the other coil (called the secondary winding). Degaussing coil-a coil used to demagnetize parts. 2  Voice coil-a coil used in a moving-coil loudspeaker, suspended between the poles of a magnet. 3  When the audio signal is passed through the coil, it vibrates, moving the attached speaker cone to create sound waves.
