Consider the current transformer of Problem 2.32.

a. Use MATLAB to plot the percentage error in current magnitude as a function of the magnitude of the burden impedance (i) for a resistive burden of 100 Ω < Rb < 1000 Ω and (ii) for a reactive burden of 100 Ω < Xb < 1000 Ω. Plot these curves on the same axis.

b. Next plot the phase error in degrees as a function of the magnitude of the burden impedance (i) for a resistive burden of 100 Ω < Rb < 1000 Ω and (ii) for a reactive burden of 100 Ω < Xb < 1000 Ω. Again, plot these curves on the same axis.
