Answer / neeraj pandey

In a DG (Diesel Generator) Electrical Generator is driven by
Diesel Engine. this engine coupled with the rotor of
generator which is made of permanent magnet.

as the magnet revolves, magnetic field also revolves with
respect to stationary Stator conductor.

Due to relative motion between Stator conductor and magnetic
field voltage is developed on generator terminals.

Answer / ash

It is basically made up of Engine+Alternator.
Engine is used as Prime mover.
When alternator is rotated with the help of Engine,current
is produced.
Alternator is just the reverse of a Electric motor.When we
apply current to motor,electrical energy is converted in to
Mechanical energy.
DG converts Chemical energy in to Mechanical energy in to
electrical Energy.

Answer / venkatesan

dg is converted the mechanical energy to electrical energy.
principle of the alternater is right hand rule of flemming.

There are 2 Flip_Flop with logic between them. Given Clock to Q delay, logic prop. delay, set up and hold times specify maximum clock frequency of system. What happens if second output fed back to first input. Any changes? What happens with timing if second output is fed back to logic between the flops? Good Luck!
