I'm somewhat confused about this law, but am afraid to ask in class. I'm hoping someone can help me out some.
I understand that current entering a point is positive, and current directed away from that point is negative. The algebraic sum of currents entering and leaving a point must equal to zero.
Where I am somewhat confused is when I have two voltage sources, both are 10V for example. Each in series with a 1 ohm resistor, with a 1 ohm resistor in parallel with both voltage sources.
To find IR voltage drops plus each branch I, I must know current total. Do I have it correct that voltage total is Vs1 + Vs2, Rt = R1 + R2 + R3, then It = 20V/3 ohm? Then Itotal from the assumed current flow is positive and I flowing from the negative terminal of the other voltage source is negative? So VR1 = I1R1, VR2 = I2R2, VR3 = I3R3, and I1 = VR1/R1, I2 = VR2/R2, I3 = VR3/R3.
I am actually very confused. Hopefully someone can clear this up for me. Attached is the diagram of the circuit. Thanks in advance!
