Help me, to understand kirchoff's voltage law.

[sphyics]

N.B: I was trying to apply kirchoff’s voltage law to this ckt diagram. (created by myself )

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

-I₁R₁ + E2 - I₁R₂ + E1 = 0

Right.

Thank you Doc Al
