I have 1 hour. Can you do it quickly?
For the given resistive network electrical circuit below:
R4
R1 3k
3k
R5
R3
2k
R6
20
2k
a) Find I and VR, if R4 is shorted.
b) Find Vab and PR, if R is opened.
c) Find the equivalent Thevenin Circuit between the terminal points a and b.
d) If R is replaced with another value, what is this value for maximum power transfer to R? Then determine the maximum power transfer.
Note: The above parts (a, b, c, and d) are to be solved separately and there is no relation between them.
