6.5. As an artist, Mihaela creates pieces lit with LEDs that can change colour. Changing the colour of the light ...

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.
