INDUCTANCEDC CircuitsInductors in parallel are combined like resistors inFigure 5 Inductors in Parallelparallel as given by Equation (3-3).(3-3)1L_{eq}1L_{1}1L_{2}. . .1L_{N}When only two inductors are in parallel, asshown in Figure 5, Equation (3-3) may besimplified as given in Equation (3-4). As shownin Equation (3-4), this is valid when there areonly two inductors in parallel.(3-4)1L_{eq}L_{1}L_{2}L_{1}L_{2}Inductors will store energy in the form of a magnetic field. Circuits containing inductors willbehave differently from a simple resistance circuit. In circuits with elements that store energy,it is common for current and voltage to exhibit exponential increase and decay (Figure 6).Figure 6 DC Current Through an InductorES-03 Page 4 Rev. 0
