Alternating Current Question 12
Question 12 - 30 January - Shift 2
In an ac generator, a rectangular coil of 100 turns each having area $14 \times 10^{-2} m^{2}$ is rotated at $360 rev / min$ about an axis perpendicular to a uniform magnetic field of magnitude $3.0 T$. The maximum value of the emf produced will be V. $(.$ Take $.\pi=\frac{22}{7})$
Show Answer
Answer: (1584)
Solution:
Formula: Self induction
$\xi _{\max }=NAB \omega$
$=100 \times 14 \times 10^{-2} \times 3 \times \frac{360 \times 2 \pi}{60}$
$=1584 V$
