a) The load resistance is 20 ohms, and the load current harmonics up to the 11th component are analyzed by Fourier analysis.
Please specify. Calculate the effective value of the load current and the total harmonic distortion.

b) Calculate of the load's apparent power (S), active power (P), reactive power (Q), Distortion power (D), Power factor (PF) .

c)Calculate source's apparent power (S), active power (P), reactive power (Q), Distortion power (D), Power factor (PF).
