Your Friend Saad was selected to attend the
Electronics workshop on “Electronic Circuits"
organized by the university. In the workshop, he was
exposed to many topics such as voltage divider
circuits, dependent voltage source, dependent
current
source,
independent voltage
source,
independent current source, application of Thevenin
and Norton theorem, maximum power transfer.
There were some customers’ requirements same
were discussed in the workshop. Apply the concepts
of the above-mentioned topics, each participant must
fulfill the customer requirements.
I) The input available DC voltage is 220 V and
customer wants to supply the output of 30V
and 50V. The available ready stock is source
voltage as mentioned above and resistors
values can be chosen from 1-300 KQ. Apply
the concept of voltage divider with values of
resistance is in k2, one value of the resistor is
the last digit of your NUTECH ID and other
may vary (depend on your calculations).
II) Now you have two…
