A) 104 W
B) 2.5 kW
C) 5 kW
D) 10 W
Correct Answer: B
Solution :
Here, \[{{V}_{0}}\,\,=\,\,100\,V,\,\,{{I}_{0}}\,\,=\,\,100A\] and phase difference \[\phi =\,\,\frac{\pi }{3}\] \[P={{V}_{rms}}\times {{I}_{rms}}\times \cos \,\,\phi \] \[=\,\,\,\frac{{{V}_{0}}{{I}_{0}}}{2}\,\cos \,\,\phi \] \[=\,\,\,\,\frac{100\times 100}{2}\times \frac{1}{2}\] \[= \,2500 W=2.5 kW\]You need to login to perform this action.
