A) \[{{I}_{0}}=25\,\,A\]and \[f=100\,\,Hz\]
B) \[{{I}_{0}}=50\,\,Hz\] and \[f=50\,Hz\]
C) \[{{I}_{0}}=50A\] and \[f=100\,\,Hz\]
D) \[{{\text{I}}_{0}}=25A\]and \[f=50\,\,Hz\]
Correct Answer: C
Solution :
From standard equation, we have \[I={{I}_{0}}\,\,\sin \omega t\] ?..(i) Given, \[I=50\,\,\sin \,\,314\,t\] .....(ii) Comparing Eqs. (i) and (ii), we get \[{{I}_{0}}=50A,\,\,\omega =2\pi f=314\] \[\Rightarrow \] \[f=\frac{314}{2\times 3.14}=50Hz\]
