B)60 V.
C)120 V.
D)240 V.
E)none of the above

Question

Quizplus · Accepted Answer

The voltage across the secondary terminals of the transformer can be calculated using the formula:

Vp/Vs = Np/Ns

where Vp is the voltage across the primary terminals, Vs is the voltage across the secondary terminals, Np is the number of turns in the primary coil, and Ns is the number of turns in the secondary coil.

Substituting the given values:

120/Vs = 50/25

Simplifying,

Vs = (120 x 25)/50

Vs = 60 V

Therefore, the voltage the transformer delivers is 60 V.
