    Assignment 1(Spring 2020)
    Circuit Theory (Phy301)
    Marks: 25
    Due Date: May 29, 2020
    DON’T MISS THESE Important instructions:

    • To solve this assignment, you should have good command over first 8 lectures.
    • Upload assignments properly through LMS, (No Assignment will be accepted through email).
    • Write your ID on the top of your solution file.
    • All students are directed to use the font and style of text as is used in this document.
    • Don’t use colorful back grounds in your solution files.
    • Use Math Type or Equation Editor etc for mathematical symbols.
    • This is not a group assignment, it is an individual assignment so be careful and avoid copying others’ work. If some assignment is found to be copy of some other, both will be awarded zero marks. It also suggests you to keep your assignment safe from others. No excuse will be accepted by anyone if found to be copying or letting others copy.
    • Don’t wait for the last date to submit your assignment.
    • You can draw circuit diagrams in “Paint” or in “Corel Draw” or circuit maker. The simple and easy way is to copy the given image in Paint and do the required changes in it.

    Q: 3:
    (I) What causes positive and negative charge?
    (II) How the electrons in last orbit of an atom responsible for stability of an atom.

    Answer:
    (I) An atom is generally considered neutral having equal no of electrons and protons.
    When an atom loses electron(s) it becomes positively charged and when an atom gains electron(s), it becomes negatively charged. In other words, deficiency of electron causes positive (+) charge and addition of electron causes negative (-) charge.
    (II) Electrons in outer orbit, also called valence electrons are loosely bound to its nucleus and can share to nearby outer orbit electrons of another atom. The atom is considered unstable as they share electrons to another atom. An atom of tightly bound electrons is more stable.

    Q: 1:
    For the given below circuit, Calculate the Equivalent resistance and current of the circuit.

    Solution:
    Calculating the Equivalent resistance
    Reduce the circuit to one equivalent resistance value.
    R1 and R2 are connected directly in parallel and can be replaced with an equivalent resistor,
