In a balanced three-phase circuit the line voltage magnitude is \(V_{\mathrm{L}}=9.8 \mathrm{kV}\) (rms). For a positive phase sequence:

(a) Find all of the line and phase voltage phasors using \(\mathrm{V}\) \(\mathrm{AB}\) as the phase reference.

(b) Sketch a phasor diagram of the line and phase voltages.
