If the current through the inductor (L 34.8 mH) at 448 Hz has an amplitude of 55 mA, what is the amplitude of the AC voltage?What is the rms value of the AC voltage?
Inductive Reactance X? 2πfL 98 ohms E I*X 55 mA x 98 ohms 5.39 volts The problem is, what do you mean by amplitude ? Voltages are measured in peak, peak-peak, or RMS. If none are stated, RMS is assumed. So lacking a meaning for amplitude, I have to assume they are in RMS current and voltage. So the RMS answer is 5.39 volts RMS. .
