what is the tranformation of energy that must occur to change your energy to electricity
Why must neutrons in a chain reaction be controlled?
Neutrons in a nuclear fission chain reaction must be controlled for two reasons... First, they must be moderated, or "slowed down", to exactly the right level of energy required to sustain the reaction. This is because, initially, the neutrons are too fast to sustain the fission reaction. They must be slowed down, but not too much, otherwise the reaction will stop. Second, they must be controlled. You want the reaction to proceed at an orderly pace, at a constant rate. To do this, you need, on a statistical average, exactly one neutron to go on to fission one atom to produce one parcel of binding energy release and one neutron, to repeat without multiplying or dividing. This is what we call KEffective = 1, where the rate of reaction does not change. Moderation and control. In tight balance. Easily upset. Fortunately, when upset, the tendency is to shutdown. That is engineering safety.
How is the controlled release of nuclear energy in a reactor accomplished?
controlling a chain reaction
What is a braking resistor?
A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. Read more at the link provided below.
How is solar energy controlled or processed?
no
How is thermal Energy Controlled?
with a thermostat
Is nuclear energy good for humans and the environment?
Nuclear energy provides electricity which is good for humans, and for the environment it does not produce greenhouse gases, so that is good. However it has dangers too, so must be well controlled
In an experiment what are controlled variables?
Controlled variables are quantities that must remain constant.
What energy is 'light is blocked?
the path that a controlled
What energy is it when light block?
the path that a controlled
What is the energy transfer in a nuclear reactor?

How energy is controlled by biogas?
It isn't. Fuels such as biogas store energy, they don't control it.
Is zofran a controlled substance?
No it is not, but you must have a prescription for it.
Define thyristor controlled braking resistor?
A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. A thyristor (also known as a silicon-controlled rectifier or SCR) is a diode which has a gate terminal on it. Current at the gate allows the thyristor to go into a conducting mode, allowing current to pass. Modern drives will detect when their DC bus voltage reaches a certain threshold (from the energy being returned from the motor during braking) and begin triggering the thyristor periodically (typically PWM, pulse-width modulation) to disperse this energy as heat. See links.
Why the generation of electricity in a power station is controlled energy?
Controlled energy basically means that (a) the rate of energy production (the power) is just the rate desired, and (b) energy is not generated so fast that it causes destruction (as would be the case in a lightning, or an atomic bomb).
