For the following question, the aim is to find the value of I_3 through the 15ohm resistor, but apparently I have a mistake in the equations I set up, using loops (kirchoffs second law) - could someone please help me find the mistake?
Working and diagram of question I colour coded to make it clear to myself that i3=i1+i2
I am unsure what your convention is for writing positive and negative potential differences. Based on your right mesh/loop (yellow coloured and green coloured lines), you move clockwise through the cell, which is a potential drop, it should be -V2 and based on your assigned current direction, I have -V2 - I2(1000) - I3(15) = 0
Then I have a further q - for part b which polarity for both the capacitors do you take, since you have to assume they act like cells for kirchoffs laws?
