May I ask,

On this page: Volume II - AC » Reactance And Impedance -- R, L, And C »

The rectangular notation for the amperage of the inductor is shown as -28.490m + j32.516m

When I use tan-1(32.516/-28.49) I get -48.78 (180 degrees out) now if I flip the angle to 131.22 shouldn't the voltage also flip from 43.232 to -43.232?

my method of conversion works fine for converting the resistor's amperage (and all problems up until now) from rectangular to polar. what is unique about this problem?-

thank you in advance- Michael
