Assignment 1(Fall 2012)                        

Circuit Theory (Phy301)

Marks: 25

Due Date: November 05, 2012

 

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).
  •  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”. The simple and easy way is to copy the given image in Paint and do the required changes in it

Q 1:

Find the equivalent resistance RT of given circuit. Write each step of the calculation to get maximum marks. Draw the circuit diagram of each step otherwise you will lose your marks.  

 

Ans:        RT = 13.869 omega

 

 

Q 3:

      Answer the following questions.  

              I.      If you wish to increase the amount of current in a resistor from 100mA to 150mA by changing the 20V source, by how many volts should you change source? To what new value should you set it?

 

Ans:    V= 30volts 

 

        II.       How much power is produced by 500mA of current through a 4.7kΩ resistor?

 

Ans:   P= 1.175kW

 

       III.      There are four equal value resistors in parallel with a 12V source, and 4mA of current from the source. What is the value of each resistor?

 

 

Ans:  The value of each resistor is = 3k omega

 

 

 

 

 




Q1 is okay ... but how can we draw circuits?

thanks  

Microsoft visio , Circuit shope, and many other software are use for this purpose. 

Q 1:

Find the equivalent resistance RT of given circuit. Write each step of the calculation to get maximum marks. Draw the circuit diagram of each step otherwise you will lose your marks.  

 

Ans:        RT = 13.869 omega


is k bh k hum solve kase kare gy means circuit solve kaha se karna start kare gy?

Qs No 1:

 

We start from the right top side

  • 20 omega and 30 omegas are in parallel so we solve it by using parallel formula. Ans will b 12 omega and then solve remaining circuits. 

For Qs No I : 

see this solve example . which is almost same to the given Qs in Assignment

brother images ma Rt=10 calculate kia hai aur oper answer Rt=13.869 post kia hai explain krain gy plz?

bhai ye to example hai .... Assignment me diya gya qs nai hai ... ye sirf samjhany k lyee tha ... 

Its not 3 k it wrong you must recalculate it
