A) 300V
B) 90V
C) 45V
D) 23V
Correct Answer: C
Solution :
Transformation ratio \[{{N}_{s}}:{{N}_{p}}=3:2\] Potential in primary \[{{E}_{p}}=30V\] From the relation, we have \[\frac{{{E}_{s}}}{{{E}_{p}}}=\frac{{{N}_{s}}}{{{N}_{p}}}\] \[{{E}_{s}}={{E}_{p}}\frac{{{N}_{s}}}{{{N}_{p}}}\] \[=30\times \frac{3}{2}=45\,V\]You need to login to perform this action.
