INDUCTANCEDC CircuitsSummaryThe important information on inductors is summarized below.Inductance SummaryWhen an inductor has a DC current flowing through it, the inductor will storeenergy in the form of a magnetic field.An inductor will oppose a change in current flow by the CEMF induced whenthe field collapses or expands.Inductors in series are combined like resistors in series.Inductors in parallel are combined like resistors in parallel.The time constant for an inductor is defined as the required time for thecurrent either to increase to 63.2 percent of its maximum value or to decreaseby 63.2 percent of its maximum value.ES-03 Page 8 Rev. 0
