Diode circuitsFor each circuit below, use the diode approximation with forward dropVF= 0.7 V to find the output voltage. No current flows to the output.

A 3-phase full-wave bridge rectifier is built using six power diodes numbered 1 to 6. The phase sequence of the 3-phase source is ABC and the line to line voltage is 440 V. The line to neutral voltage of phase A has an angle of -30 degrees. The anodes of the diodes 1, 2, 3 are connected to phase A, B, and C, respectively, and the cathodes of diodes 1, 2, and 3 are connected to a common terminal that serves as the positive terminal of the rectifier's output. The cathodes of diodes 4, 5, and 6 are connected to phase A, B, and C, respectively, and the anodes of diodes 4, 5, and 6 are connected to a common terminal that serves as the negative terminal of the rectifier's output.  If diode 1 is damaged and acts as an open circuit, what would the RMS voltage be at the load?
