What Are the Maximum and Minimum Voltages Generated by a Generator?

Click For Summary
The discussion focuses on calculating the maximum and minimum voltages generated by a generator with specific parameters, including a rotor frequency of 10 Hz. The maximum voltage is initially calculated as 3141 V using the formula ε = Βlv, but later revised to 1000 V based on further clarification of the equations. The minimum voltage is confirmed to be 0 V, as it is a standard condition for generators. Participants seek confirmation and assistance with their calculations and understanding of the formulas used. The conversation highlights the importance of accurately applying generator equations to determine voltage outputs.

Homework Statement



Hi there, motor and generator gurus

Suppose a generator has the following specifications, and the rotor turns with frequency 10 Hz. Determine the maximum and minimum value of the voltage generated, using the formula: ε = Βlv

n = 1000 loops = 1000
B = 10 Tesla
I = 10 current of coil in Ampere (A)
A = (0.05 m x 0.1 m) area of coil in m2

τorque = 500 Nm


Homework Equations



ε = Βlv maximum voltage is E0 = NABω Since ω = 2pif


The Attempt at a Solution



My solution is maximum voltage 1000 x 10 x (0.005) x 2 x pi x 10 = 3141 V

Minimum voltage = E0 = 0 (min voltage must be zero)

Assistant needed as my voltage is excessive IMO.

Cheers and thanks

I think I have worked it out, can someone please confirm.

10 Hertz converted to radians is 62.83, therefore my volts would drop to 314 V

and minumum - if e = 0, then the minimum voltage should be 0.

Cheers

Hi there, and help!

I have been attempting to nut this out and could use some guidance.

I think that I have the equation right now E(max) = 2 x n (turns) x B(in tesla)x L x v sin (theta).

Based on the info already available (see previous post) the max voltage is 1000 V.

Can someone please confirm.

Cheers
 
Anyone? Please assist.

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
