Difference between Generator and Alternator

AI Thread Summary
The key difference between a generator and an alternator lies in the type of current they produce; a generator produces direct current (DC), while an alternator generates alternating current (AC) that is converted to DC using a bridge rectifier. Generators are a broad category of devices that convert mechanical energy into electrical energy, whereas alternators are a specific type of generator designed for AC output. Additionally, a dynamo is another type of generator that directly produces DC. Understanding these distinctions is crucial for applications in electrical systems. This knowledge aids in selecting the appropriate device for specific energy conversion needs.

Hi guys,

As per topic, what actually differentiates a generator and alternator?
 
Physics news on Phys.org
One generates and one alternates... :)
 
A generator produces DC directly, an alternator produces AC which is then converted to DC with a bridge rectifier.
 
A generator is a generic term for a device which, broadly speaking, converts mechanical to electrical energy. An alternator is a type of generator which works as described by Integral, and can be contrasted with a dynamo, which directly produces DC.
 

Thread 'Rolling without slipping on a curved surface'

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 '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...
