The video tutorial covers question 13 from the book 'Introductory Circuit Analysis' by Robert Boylestad. It involves analyzing a circuit using digital multimeter readings and oscilloscope data to calculate the values of inductance (L) and resistance (R). The tutorial explains the process of determining these values using equations for V of L, X of L, and Omega, and applying Ohm's law and the Pythagorean theorem. The video concludes with a discussion on the practical application of these techniques in real-world scenarios where internal circuit configurations are unknown.

Which formula is used to calculate the inductive reactance (X_L)?

X_L = V_L / I

X_L = Omega * L

X_L = I / V_L

X_L = Omega / L

How is the peak voltage (V_p) derived from the peak-to-peak voltage in a symmetrical waveform?

V_p = V_peak-to-peak * 2

V_p = V_peak-to-peak * sqrt(2)

V_p = V_peak-to-peak / 2

V_p = V_peak-to-peak / sqrt(2)
