How can the sending-end and receiving-end voltages of a transmission line have the same magnitude?
The authors of Power Systems Analysis claim that
\begin{align}
|V_S| = |V_{R,NL}|
\end{align}
where VS is the sending-end voltage, VR is the receiving-end voltage, and VR,NL is the receiving-end voltage when there is no load. How can the magnitudes…

Why is the LM7812 getting hot in this circuit?
I have made this circuit. It works fine with normal Zener diode, however when I replaced it with the LM7812 it works fine but as time passes the regulator keeps getting very hot although the load is just 5mm LED. (I replaced it with a regulator…
