In this problem, we'll need various equations. We'll begin by identifying the necessary equations.

Rms current:

$\overline{){{\mathbf{i}}}_{\mathbf{r}\mathbf{m}\mathbf{s}}{\mathbf{=}}\frac{{\mathbf{V}}_{\mathbf{r}\mathbf{m}\mathbf{s}}}{{\mathbf{X}}_{\mathbf{L}}}}$ where V_{rms} is the rms voltage and X_{L} is the inductive reactance

Rms Voltage:

An inductor is connected to an AC power supply having a maximum output 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?
