Is there an electrical generator that will put out more power than it consumes so as to create a self sustaining reaction with some to spare?
Ganderton
Energy is constant, it cannot be created or destroyed; it simply changes form. Therfore, this electrical generator is impossible. The best efficency is approx. 30%. The other 70% of theenergy comes out as usless vibration, sound or light. The generator mentioned in the question would gain energy from nowhere, in other words, it's Science Fiction.

A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What is the name of a chemical reaction that gives out energy?
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
What causes an increase of speed in a combustion reaction?
There are three things needed for combustion: heat, oxygen, and fuel. After the reaction has started, the production of heat may fuel the reaction, making it self sustaining.
During the course of which type of reaction is energy consumed?
Any reaction that consumes energy, or has a positive delta(H), is called an endothermic reaction.
If a reaction in one direction releases energy the same reaction in the other direction will what?
absorb that same amount of energy to establish a dynamic equilibrium.
What is a self sustaining reaction called?
IT's when you put a pen on a peice of paper

Is neutron particle is required both to start and as a product in a fissin reaction?
Yes. That's how the reaction is self-sustaining: The product of one reaction is the reactant for the next.
A Self-sustaining nuclear fission chain reaction is dependent upon the release of what?
Neutrons
What is the name of a chemical reaction that gives out energy?

How can you tell the difference between an endothermic and exothermic reaction?
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
What are the four components of fire?
the four components of fire are heat, fuel, oxygen and the sustaining chemical reaction
What causes an increase of speed in a combustion reaction?
There are three things needed for combustion: heat, oxygen, and fuel. After the reaction has started, the production of heat may fuel the reaction, making it self sustaining.
What is the difference between motor and generator in electrical machine?
A motor converts electrical energy into mechanical energy and a generator converts mechanical energy into electrical energy.Longer answerThe primary difference between a motor and a generator is that one converts electrical energy into mechanical energy (that's the motor) and the other converts mechanical energy into electrical energy (that's the generator).In some cases of direct current (DC) machines, but not alternating current (AC) machines, there is so little difference that a single device (it might be called a motor-generator) can be used as either a motor or a generator.A superb example of this would be the motor-generator that is used in electric vehicles: when the vehicle is accelerated, the batteries supply power to the motor-generator and it acts as a motor, driving the wheels. When the brake is applied, the motor-generator shifts function and the vehicle's inertia is used by the motor-generator to generate electricity and put some energy back into the batteries. This slows the vehicle down. The one device (the motor-generator) is being used in either capacity. The "handle" often applied to electric vehicles with this feature is dynamic braking.They alike because they both have stators and rotors they are different in that the generator is driven by mechanical device that rotates the rotor, the rotor cuts through magnetic force fields and electricity is generated. The motor is driven by an input of electricity into the stator and the rotor is forced to turn by reaction with magnetic force fields.Generator will provides current to load ......... but motor will drawn current............... generator is based on Flemming right hand rule but motor is based on left hand rule.
What happens at the rated value of the voltage of the generator?
The rated voltage of a generator decreases due to many causes such as armature reaction, overloading of the generator and AVR failure/ weak excitation voltage.
How do batteries transform energy to electrical energy?
They convert a chemical reaction into electrical energy.
What is it called when neutrons released from a fission event cause other fission events in a continued self sustaining cascade?
A chain reaction
