(a) The circuit in Figure 13-26 has a square wave input. What is the highest frequency that can be used and still observe the complete waveform across the inductor?
(b) Assume the generator is set to the frequency determined in (a). Describe the voltage waveform across the resistor?

(a) \tau =\frac{L}{R}=\frac{15 \ mH}{33 \ K\Omega } = 0.454 \ ms
The period needs to be 10 times longer than \tau observe the entire wave.
T= 10\tau = 4.54 \ \mu sf=\frac{1}{T}= \frac{1}{4.54 \ \mu s} = 220 \ kHz
(b) The voltage across the resistor has the same shape as the current waveform. The general shape was shown in Figure 13-24 and has a maximum value of 10 V (the same V_{s} assuming no winding resistance).
