Y/ Y+delta transformer. The primary line voltage is 6.3 kV.
i. Draw the connection diagram.
ii. Determine the phase voltages of the two secondary windings of the transformer.
iii. Determine the transformer turn's ratio (Y/Y and Y/delta) and the transformer volt ampere ratings.
iv. Calculate the diode ratings.
v. Draw to scale the output voltage as well as the diode anode to cathode voltage waveforms.
vi. Calculate the output voltage ripple.
the light also changes how her art work appears visually. This type of art work is known as chromatic manipulation Mihaela powers her circuits using four cells with a voltage of 6.0 V each. To protect the LEDs, the cells must be in series with a 10 Ωresistor.Draw a circuit with which Mihaela could light her artwork using three LEDs. Each LED must be able to be turned off individually, so the colour output can be selected.
