By Starting This Assignment You Agree To These Condition.

This assignment is my own work and I am ready to answer any questions that are being posed at me regarding this assignment, teacher may ask me solution method of individual question.

I am completely aware if it is found that there is plagiarism in this assignment I will be awarded ZERO marks even if the plagiarism is found in any of the question.

I agree to that fact that my assignment will undergo through one or multiple plagiarism checking algorithms and if their result suggests that there is plagiarism then I too agree with it.

If in any case my final answer doesn’t match my calculations I am aware that I will be awarded zero for that specific question.

Answer table is filled in accordance with my assignment and I am completely aware that if it is found that answer table’s value doesn’t correspond with my solution I will be awarded ZERO marks.

Important Instructions

· All Answers should be written correct to 2 decimal places rounded up in all conditions, for example: Ans = 2.251 => 2.26, Ans = 1.529 => 1.53

· All step by step working should be shown.

· This assignment’s solution is only acceptable when done using any text editor hand written solution is not acceptable.

· Solution should be written in table provided for it you may add more rows in that table if required all steps are to be shown.

· Do not use Curly Brackets { } and Square Brackets [ ] use Only Round Brackets ( ) in your solution.

· Do not use word’s equation for example : => use instead this format => (X^3/23)*Y^2

· All diagrams of equivalent circuits to be pasted at the end of this assignment in question wise ascending order, with Question Number clearly mentioned on each diagram. If this is not followed particular diagram will not be considered as part of this assignment.
