Q.1:

Find the equivalent resistance across A and B, of given circuit network. Write each
step of the calculation to get maximum marks. Draw the circuit diagram of each step
otherwise you will lose your marks. (can use electronic work bench to verify Q.1, 2)
[Marks:10]




Answer
Step 1
5Ω and 7Ω resistor are presented in series. Let equivalent resistance is




R5,7 =5Ω+7Ω=12Ω

, Step 2
12 Ω parallel 7 Ω now equivalence resistance is

12× 4 48
R12,4 = = = 3Ω
12+ 4 16




Step 3

Now again we see what is parallel so 3Ω is parallel to 3Ω

3× 3 9
R3,3 = = = 1,5Ω
3+3 6
