Hi all.
Please take a look at the attached AC-circuit.
My question is: If this was a DC-circuit, then it would be a piece of cake to solve Kirchhoff's laws, since we would just define a positive direction, and see which direction the power supplies would want the currents to run in.
But this is an AC-circuit, so I guess it does not make sense to ask which way the power supplies want the currents to run in. So how will the lefthand-side of Kirchhoffs law for the "largest" loop like?
Is it: ε_1 - ε_2 = ...., or is it: ε_1 + ε_2 = ....? And is there a general way to determine this?
Thanks in advance.
Sincerly,
Niels.
