Achieve a given revised spec The customer has a LED circuit box with the following configurations. An op-amp, a 1.5V
input battery, a iko input resistor and a 2kg feedback resistor It is used to light up a 1.2
to ZV LED with a 1000 resistor connected in series at output terminal "a" and "b".
Now the customer would like to use this box to operate with a total number of 6 different
changing the value of one of the components
colours of LEDs to make a light chain (6 LEDs connected in series) and place it in his office
reception. The output terminal voltage shall be increased to +12V. One more condition,
the company would like to have the circuit as simple as possible.
Note: An internal 15V battery pack is installed in the op-amp and so you do not need to
consider the power supply to the op-amp in your design.
