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