A) 100 acV
B) 120 ac V
C) 110 acV
D) 220 ac V
Correct Answer: C
Solution :
For a transformer, \[\frac{{{V}_{s}}}{{{V}_{p}}}=\frac{{{N}_{s}}}{{{N}_{p}}}\] where N denotes number of turns and V = voltage. \[\therefore \,\,\frac{{{V}_{s}}}{220}=\frac{10}{20}\] \[\therefore \,\,{{V}_{s}}=110\,ac\,V\]You need to login to perform this action.
