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 and current flowing through equivalent 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 2kΩ resistor for the given circuit. Mention the units of calculated value.
Q 3:
Answer the following questions.

I. Write the differences between alternating current (AC) and direct current (DC).

II. A 12V battery is connected across two series resistances of value 2kΩ and 6kΩ. Determine the voltage drop across 6kΩ resistor.




III. What does the term “Conventional current” and “Electron current” mean?
