Hi,
when summing the votages when using Kirchoff's voltage law around some loop, why do anywhere they take L(dI/dt) as the voltage fall on the inductance (if we sum the voltage in the current direction)?
If I understand well , if there is a current in some direction, the induced voltage (according to Lenz's law) will be in the opposite direction, so it will tend to cancel the original current, so the voltage will be -L(dI/dt).
Am I wrong?
