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).
1 trillion = (1 thousand)3+1 = (103)4 = 1012. so 1 trillion has 13 digits (a '1' followed by twelve '0's). * In those countries that use the long scale (based on powers of a million) like Europe: 1 trillion = (10^6)^3 = 10^18 which is 1 followed by 18 zeros, ie 19 digits.
