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