47. (a) Voltage is proportional to inductance (by Eq. 30-35) just as, for resistors, it is proportional to resistance. Since the (independent) voltages for series elements add ( V 1 + V 2 ), then inductances in series must add , eq 1 2 LL L = + , just as was the case for resistances. Note that to ensure the independence of the voltage values, it is important that the
