Solution 6:
Here we have symmetry of resistances and current:
Hence




Hence we see symmetry:
AB is Symmetric to AD
Hence:
Hence answer is part 2
Solution 7:
Resistance R5 is:







Hence answer is part 6
Solution 8:
Voltage at node b:
Voltage at node f:
Hence the Voltage across Ebf is:
Hence answer is part 4
Solution 9:
The direction of current will be reversed.
Solution 10:
Hence solution is Part 2
Solution 11:
Hence solution is Part 1
Solution 12:
To find the polarity of capacitor:
Hence positive polarity is on node C and negative polarity is on node F
Hence solution is part 2
