Phy301 Circuit Theory Assignment No.1 Fall 2012 Last Date November 5, 2012
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.
Q 2:
Determine VR1, R2, and R3 for the given circuit. Mention the units of calculated value.
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?
II. How much power is produced by 500mA of current through a 4.7kΩ resistor?
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?
