A three phase balanced star connected voltage source with frequency \(\omega\) rad/s is connected to a star connected balanced load which is purely inductive. The instantaneous line currents and phase to neutral voltages are denoted by (\(i_a\), \(i_b\), \(i_c\)) and (\(v_{an}\), \(v_{bn}\), \(v_{cn}\)) respectively, and their rms values are denoted by V and I. If \(R = [v_{an} \ v_{bn} \ v_{cn}] \begin{bmatrix} 0 & \frac{1}{\sqrt{3}} & -\frac{1}{\sqrt{3}} \\ -\frac{1}{\sqrt{3}} & 0 & \frac{1}{\sqrt{3}} \\ \frac{1}{\sqrt{3}} & -\frac{1}{\sqrt{3}} & 0 \end{bmatrix} \begin{bmatrix} i_a \\ i_b \\ i_c \end{bmatrix}\), then the magnitude of R is

Suppose we define a sequence transformation between "a-b-c" and "p-n-o" variables as follows: \(\begin{bmatrix} f_a \\ f_b \\ f_c \end{bmatrix} = k \begin{bmatrix} 1 & 1 & 1 \\ 1 & \alpha^2 & \alpha \\ 1 & \alpha & \alpha^2 \end{bmatrix} \begin{bmatrix} f_p \\ f_n \\ f_o \end{bmatrix}\), where \(\alpha = e^{j\frac{2\pi}{3}}\) and k is a constant. Now, if it is given that: \(\begin{bmatrix} V_p \\ V_n \\ V_o \end{bmatrix} = \begin{bmatrix} 0.5 & 0 & 0 \\ 0 & 0.5 & 0 \\ 0 & 0 & 2.0 \end{bmatrix} \begin{bmatrix} i_p \\ i_n \\ i_o \end{bmatrix}\) and \(\begin{bmatrix} V_a \\ V_b \\ V_c \end{bmatrix} = Z \begin{bmatrix} i_a \\ i_b \\ i_c \end{bmatrix}\), then,
