## Main Question or Discussion Point

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

Am I wrong?

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?
