The increase in resistance due to non-uniform distribution of current in a conducto $$r$$ is known as _______effect

In a system, there are two generators operating in parallel. One generator, of rating 250 MVA, has an inertia-constant of 6 MJ/MVA while the other generator of 150 MVA has an inertia-constant of 4 MJ/MVA. The inertia-constant for the combined system on 100 MVA common base is ________MJ/MVA.

In a power-system, the $$3$$-phase fault MVA is always higher than the single-line-ground fault MVA at a bus (State True or False)

HVDC transmission is preferred to EHV __ AC because
