In an ideal inductor that has no resistance or capacitance, as the current increases energy flows into the inductor and is stored there within its magnetic field without loss, it is not released until the current decreases and the magnetic field collapses.
On the short scale, there are 12 zeros in a trillion (1012). It is 1,000,000,000,000. The traditional long scale, still used in many areas of the world, advances number names by millions, with intermediate names for the thousands (milliard, billiard, trilliard).
A trillion is a million million, written as 1 plus 12 zeros. When government spending gets into the trillions, as it soon will, do the calculation for billions described above and add three zeros. For our next lesson weâll learn the difference between a jillion and a gazillion. Class dismissed.
