A transformer connected to a 240(V_{r.m.s}) has 3000 turns in its primary coil and 500 turns in its secondary coil. Calculate the output voltage.
-
A.
4000V -
B.
400V -
C.
40V -
D.
4V
Explanation
(N_{p} = 3000 turns)
(N_{s} = 500 turns)
(E_{p} = 240V_{r.m.s})
(E_{s} = ?)
(frac{N_{s}}{N_{p}} = frac{E_{s}}{E_{p}})
(frac{500}{3000} = frac{E_{s}}{240})
(implies E_{s} = frac{240times500}{3000} = 40V)
