PHY301 Circuit Theory Assignment No.1 Solution Spring Semester 2013


Assignment 1(Spring 2013)
Circuit Theory (Phy301)
Marks: 25
Due Date: April 29, 2013

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 loose marks.

Q 2:
Determine the voltage and current across each resistor for the given circuit. Mention the units of calculated value.


Q 3:
Answer the following questions.

I. Why a crow sitting on high voltage bare line, does not get electric shock?

II. A 100 Watt light bulb operates on 140V.How much current does it require?

III. Write the names of different instruments/devices used to measure the voltage and current across a circuit element & way know to connect them.
