A) 90V
B) 120V
C) 220V
D) 30V
Correct Answer: B
Solution :
[b] Magnetic flux linked with primary coil \[\phi ={{\phi }_{0}}+4t\] \[{{e}_{p}}=\frac{d\phi }{dt}=4V\] Transformer ratio \[\frac{{{N}_{p}}}{{{N}_{p}}}=\frac{{{V}_{p}}}{{{V}_{s}}}\] \[\frac{50}{1500}=\frac{4}{{{V}_{s}}}\] \[{{V}_{s}}=120V\]You need to login to perform this action.
