A) \[\frac{{{10}^{4}}\times {{8}^{2}}}{25}V\]
B) \[\frac{{{10}^{4}}\times 8}{25}V\]
C) \[\frac{{{10}^{4}}}{25\times 8}V\]
D) \[\frac{{{10}^{4}}}{25\times {{8}^{2}}}V\]
Correct Answer: B
Solution :
[b] \[P={{V}_{1}}{{i}_{1}}={{V}_{2}}{{i}_{2}}\] \[{{V}_{2}}=\frac{{{10}^{4}}}{25}\] Now \[{{V}_{1}}=\frac{{{n}_{1}}}{{{n}_{2}}}\times {{V}_{2}}=\frac{8}{1}\times \frac{{{10}^{4}}}{25}\,V\]
