Help me, to understand kirchoff's voltage law.

AI Thread Summary
To apply Kirchhoff's Voltage Law (KVL) correctly, it is essential to assume the current direction in each branch of the circuit. In this case, the circuit has only one branch, meaning the current remains consistent throughout. The equation derived from the circuit analysis is -I1R1 + E2 - I1R2 + E1 = 0, confirming the application of KVL. The discussion highlights the importance of understanding current direction and branch configuration in circuit analysis. Overall, clarity in these concepts is crucial for accurate electrical calculations.

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

Right.
 
Thank you Doc Al :smile:

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
