[QUOTE="msb2003, post: 57709, member: 3816"] I think a couple are wrong!! Power is the rate at which work is done so Power = Work / Time (shown as Power = work x time) And the voltage calculation works if your talking about the Voltage across the resistor and the voltage across the Inductor so the symbols should read Vr and Vxl not just R and Xl. The calculation shown would give impedance using resistance and inductive reactance as stated by andyc [/QUOTE]
