# PHY301 Circuit Theory Assignment No 1 Solution and Discussion due date; 17-11-2014

PHY301 Circuit Theory Assignment No 1 Solution and Discussion due date; 17-11-2014

# Assignment 1 (Fall 2014)

Circuit Theory (Phy301)

Marks: 30

Due Date: November 17, 2014

Don’t miss these important instructions:

• To solve this assignment, you should have good command over first 6 lectures.
• Upload assignments properly through LMS, (No Assignment will be accepted through email).
• 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” in “MS Visio” or in circuit maker. The simple and easy way is to copy the given image in “Paint” and do the required changes in it.

Q. No: 1

A 30V battery is attached to a circuit containing 2 resistors and a fan having 3Ω resistance.      Marks 12

1)      Calculate the source current Is.

2)      Determine the voltages V1, V2, and V3.

3)      Calculate the power dissipated by each resistor.

4)      Determine the power delivered by the source, and compare it to the sum of the power levels of part (4)

Q. No: 2

Find the equivalent resistances RT of given circuit. Write each step of the calculation to get maximum marks. Draw the circuit diagram of each step otherwise you will loose marks.        Marks 10

Q. No: 3

Answer the following short questions.     Marks 8

1.               I.      An energy saver, of 25 watts is connected across 220V energy source. Calculate the current flowing through it.
2.            II.      Give two examples of closed circuit and open circuit from daily life.
3.          III.      Given below are some materials. Mention the conductor, semiconductor and Insulator from them.

Silicon, Silver, iron, carbon, glass, copper, rubber.

Q. No: 1
A 30V battery is attached to a circuit containing 2 resistors and a fan having 3Ω resistance. Marks 12

1) Calculate the source current Is.

formula : I=V/R

Q3)power desipation : P=I^2 R(its means I square into R)

Q no 2)

Rt=R1+R2

I={R2\(R1+R2) }*I

req= (R1.R2)\(R1+R2) formula

Hint for Q no 2 these formulas will be used in the Solution

Dear Students Don’t wait for solution post your problems here and discuss ... after discussion a perfect solution will come in a result. So, Start it now, replies here give your comments according to your knowledge and understandings....

I want to know that which type of changes occur in circuit diagram as in assignment they tell us in instruction that "You can draw circuit diagrams in “Paint” in “MS Visio” or in circuit maker. The simple and easy way is to copy the given image in “Paint” and do the required changes in it." so plz tell me which type of change we done??????

@ Ammy Dollie : It's mean that calculate the equivalent resister and then re-draw the diagram until it reached the decision of at least the 1- resister. i.e .If only one resister apply here  instead of all resister.

koi ye to btaey k , agay q1 kesy solve ho ga?

complete solution share kry plzzzzzzzzzzzzz

here is the complete solution file of  assignment phy 301 ............... notify me for any kind of mistake...........
