Peak voltage output of a generator

AI Thread Summary
The discussion focuses on calculating the peak and RMS voltage output of a generator with a 400-loop circular armature coil rotating in a magnetic field. The initial calculation for peak voltage output yielded an excessively high value of 2,960,881V, prompting the author to suspect an error. A critical mistake was identified in the diameter conversion from centimeters to meters, which significantly affected the result. The RMS voltage output is dependent on the corrected peak voltage, with a formula provided for calculation. The confusion around the sine function's value relates to the nature of the generator, suggesting it operates like a DC generator.

Homework Statement


A 400 loop circular armature coil with a diameter of 5cm rotates at 60rev/s in a uniform magnetic field of strength 1T.

a) What is the peak voltage output of the generator?
b) What is the RMS voltage output of the generator?

The Attempt at a Solution



a) My answer seems a tad large, I think I'm doing something wrong but can't quite pick it...
ε=NBAωsin(ωt)
ε=400*1*(pi*2.5²)*(60*2pi)*1
ε=2960881V

b) RMS=ε*[1/√(2)]
(Leaving it for now as it depends on the answer from part a)

Convert 5cm to 0.05m. Reduces answer by a factor of 10000.

Silly me...
 
why is sin(wt) = 1?

is it because its a dc generator?
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
