Why the alternator connected to grid didn't loose synchronizm in following condition?

Lets say the grid is at ideal frequency 50 hz then the large load is shut of due to which frequency increases beyond 50 which tends to rotate all turbines faster than their previous speed but at...

Why there is no current flows between B1 and B2 in Uni Junction transistor with emitter open as both the bases are on n type region?

The doping of N type is done lightly so the resistances are high between B1 and B2 but with this high resistances why electrons do not flow between B1 and B2 as leakage current flows through B2...

For a medium line model half shunt, the capacitance is lumped at each end of the transmission line. Why?

I want to know why the model behaviour is very close to original structure and why we dont lumoed capacitence only in one side. Put more than two capacitence lump on model.
