- l-why generally the voltage is applied to H.V.side?

For the following switch circuit: A) Derive the switching algebra expression that corresponds one to one with the switch circuit. B)  Derive an equivalent switch circuit with a structure consisting of a parallel connection of groups of switches connected in series. (Use 8 switches.) C) Derive an equivalent switch circuit with a structure consisting of a series connection of groups of switches connected in parallel. (Use 7 switches.)

I need the answer as soon as possible

b) Remove the following complements using DeMorgan's theorems. ______________________        ___________________                   _____________ P+ Q + (C+D.E').  (F+G)  Please write the solution handwriting.
