Help me, to understand kirchoff's voltage law.

  1. Oct 20, 2009 #1
    N.B: I was trying to apply kirchoff’s voltage law to this ckt diagram. (created by myself :smile:)

    To apply kirchoff’s voltage law:

    1) Assume current along with their directions in each branch of the ckt.
    (Assumed: and represented by arrows (red for I1 and violet for (I1 + I2) tis is wer my problem, am I right in choosing the violet arrow as (I1 + I2). Intuitively I am not convinced by my choice.

    Your circuit only has one "branch". The current is the same throughout.

    agree with the point; so the equation would be:

    -I1R1 + E2 - I1R2 + E1 = 0
