Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am hoping someone can break down an equation for me. I am used to Kirchhoff's law in the form of i_{1}+ i_{2}+ i_{3}= 0 etc. But recently in a High Frequency class, we were told ...'Let us apply the Kirchhoff's law to the equivalent circuit of a transmission line segment of length [itex]\delta[/itex]z. Using the voltage law, we get

V(z,t) = R[itex]\delta[/itex]z * I(z,t) + L[itex]\delta[/itex]z * ([itex]\delta[/itex]I(z,t)[itex]/[/itex][itex]\delta[/itex]t) + V(z + [itex]\delta[/itex]z,t)'.

If anyone could help me break this down, or explain who it relates to the general form of the equation, that would be amazing.

Many thanks in advance.
