A) \[4.5\times {{10}^{4}}W\]
B) \[4.5\times {{10}^{2}}W\]
C) \[6\times {{10}^{4}}W\]
D) \[6\times {{10}^{4}}W\]
Correct Answer: A
Solution :
The power output \[P=90%\times {{V}_{p}}\times {{I}_{p}}\] Here, \[{{V}_{p}}=2.5kV=2500V,{{I}_{p}}=20A\] Therefore, the power output \[=90%\times {{V}_{p}}\times {{I}_{p}}=90/100\times 2500\times 20\]\[=45kW=4.5\times {{10}^{4}}W\]You need to login to perform this action.
