Answer:
118.166 volt
Explanation:
We have given number of turns N =345
Sides of the rectangular coils is 12 cm =0.12 m
So area A =0.12×0.12=0.0144 [tex]m^2[/tex]
Magnetic field B =0.45 T
Angular speed =505 rpm
Speed in rad/sec [tex]\omega =\frac{2\pi N}{60}=\frac{2\times 3.14\times 505}{60}=52.8566rad/sec[/tex]
The emf is given by [tex]E=NAB\omega SIN\omega t[/tex]
For maximum emf sinwt =1
So [tex]E=345\times 0.0144\times 0.45\times 52.8566=118.166volt[/tex]
