R 1. Measure the internal resistance of the 1mH inductor. Set up the given circuit with R = 270n and L = 1mH. Apply a sinusoidal voltage as input. Adjust V, = 4Vpp and set the frequency as 20kHz. Observe the input voltage and the V, L voltage across the inductor simultaneously using an ocilloscope and plot both signals. Find the phase difference between these signals and comment on the results.

Problem 4-A 80 kHz sinusoidal voltage has zero phase angle and a maximum amplitude of 25 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady-state current has a maximum amplitude of 628.32 μA. a) What is the frequency of the current in radians per second? b) What is the phase angle of the current? c) What is the impedance of the capacitor? d) What is the capacitance of the capacitor in microfarads?
