The $3\mathrm{.}2-$MV AC electricity from a power transmission line is fed into the primary coil of a transformer. The ratio of the number of turns in the secondary coil to the number in the primary is Ns$/$Np $=85.$

$-$ Part $($a$)$

What is the voltage, in megavolts, of the output from the secondary coil of the transformer?

Vs $=272\mathrm{.}0272\mathrm{.}0$Correct$!$

$$ Part $($b$)$

The result from part $($a$)$ is much too high, well above the breakdown voltage of air over reasonable distances $($which is about a megavolt per meter$).$ Which assumption is unreasonable and responsible for this engineering error?

The ratio of the number of turns is unreasonably high.None of the assumptions are unreasonable.The input voltage is unreasonably low.The input voltage is unreasonably high.An assumption not listed here.The ratio of turns in unreasonably low.
