Expert Solution
Step 1

We have been given an generator which is having,

Radius (r) = 10 cm = 0.1 m

field strength (B) = 0.9 Wb/m2

Length of conductor (l) = 12 cm = 0.12 m

Speed (N) = 1400 r,p,m

Number of conductors are 152

 

We have been asked to find the voltage that is being generated.

 

We will first find the voltage generated in each conductor using equation as,

  = B l v

 

Where,

v = velocity so,

 

And Velocity (v) is given by,

v = ω × r

 

where,

ω = 2π N60
