Find an expression for the potential difference across the inductor.
The maximum voltage across the inductor is 0.20V when and f = 500 Khz. What is ?
A particular inductor has appreciable resistance. When the inductor is connected to a 12-V battery, the current in the inductor is 3.0 A. When it is connected to an AC source with an RMS output of 12 V and a frequency of 60 Hz, the current drops to 2.0 A. What are (a) the impedance at 650 Hz and (b) the inductance of the inductor?
An inductor is connected to an AC power supply having a maximum input voltage of 4.00 V at a frequency of 300 Hz. What inductance is needed to keep the rms current less than 2.00 mA?
