A) 300\[\pi \]
B) 3000\[\pi \]
C) 3\[\pi \]
D) 30\[\pi \]
Correct Answer: D
Solution :
Peak value of induced emf in a rectangular coil is \[e=nBA\omega \sin \theta \] \[=300\times 4\times {{10}^{-2}}\times (25\times 10\times {{10}^{-4}})\]\[\times (2\pi \times 50)\times sin{{90}^{o}}\] \[=30\pi \,volt\]You need to login to perform this action.
