construction of DC generator
A simple device for testing how vertical a construction is.
I WOULD DARE TO SAY THAT THIS IS AN OVERALL GENERAL QUESTION THAT DOES NOT HAVE A SIMPLE ANSWER. FIRST, WHAT TYPE OF CONSTRUCTION (MASONRY, FRAMING, ETC.)? AND AT WHAT LEVEL?
What picture that is displayed on a construction sign depends on what type of construction sign. The classic one is a simple text "Under Construction" or if it's road work it might say "Road work" or "Road work ahead". When it also has a picture it tends to be a man with a shovel digging.
In a very simple, laboratory-type, a.c. generator -yes. In practical generators, the output (armature) windings are part of the stator, so do not rotate and, so, don't require slip rings.
They are working in the same way that a hairdryer drys your hair. Simple.
construction and working of simple microscope
Induce current in the generator windings.
The short and simple answer is this: A wind turbine consists of blades; similar to those of a helicoptor. These blades are attached to a generator. As wind causes the blades to move, the blades turn the generator to produce electricity. As to how a generator works; I'll have to leave that up to someone else to explain.
The working principle of wind power is exceptionally simple. Wind turns the blades on a windmill and the power that is generated is stored for later use.
Generator work on the principle of conversion of mechanical energy into electrical energy.EMF - Electro-Motive Force. When a conductor passes through a magnetic field, electrons are forced to move along the conductor thereby creating 'power' (as a simple explanation).

A hydrogen fuel cell generator is quite simple in theory, but in construction it can be quite difficult. You need three airtight containers, preferably completely empty of everything, including air. Then you would need some elecrtodes, copper and zinc or nickle working well. These are just the basics. All generators require other things, but as I don't know exactly what you are aimming at, I just gave you the universal neccessities.
Either a battery or a generator
That would all depend on the construction and type of generator.A simple DC generator may use permanent magnets for the field. In this case, because the coils pass the field in the opposite direction, the output will be opposite.If the field windings are excited by an external source, the output can be controlled either way.
Well you ought to know the difference between A.C. and D.C. You have toknow the principle of the working of motor and generator. You should know the present situation of A.C. in India. You need not memorise the functioning and the structure of motor and generator. Rest is simple.

No, simple machine. It uses the spinning shaft to revolve a gear which powers a generator. Very simple.
