Why does a larger synchronous generator have a better rating

AI Thread Summary
A larger synchronous generator has a better rating primarily because its physical size allows for greater power output. The increased size accommodates more windings and larger magnetic fields, enhancing efficiency and performance. This design enables the generator to handle higher electrical loads without overheating. Additionally, the term "rating" refers to the maximum power output a generator can provide safely and effectively. Understanding these principles is essential for grasping generator performance and applications.

Homework Statement


I read in my notes that "The physical size of a synchronous generator of a particular rating is larger than one of a lower rating"

Why is this so ?

The Attempt at a Solution


Is it because a larger one would be able to supply more power and therefore the rating would be higher ?

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
