A) \[0.48\,\,V,\,\,0.0096\,\,mA\]
B) \[0.48\,\,mV,\,\,0.0096\,\,mA\]
C) \[0.24\,\,mV,\,\,0.048\,\,mA\]
D) \[0.24\,\,mV,\,\,Zero\]
Correct Answer: C
Solution :
Induced emf \[e=-\frac{d\phi }{dt}=-A\times \frac{dB}{dt}=-120\times {{10}^{-4}}\times 0.02\] Negative sign tells about the direction (polarity). Also, \[i=\frac{e}{R}=\frac{0.24}{5}=0.048\,\,mA\]You need to login to perform this action.
