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).
In Britain billion means twice as many zeros as one million or 12 zeros â1,000,000,000,000â. And trillion means three times as many zeros as one million of 18 zeros â1,000,000,000,000,000,000â. I am assuming these are students (hopefully young ones) doing homework.
