What is proportional control?
Proportional controllerA proportional controller is a type of a feed back controller where the difference between the measured output and the input (the desired output) is multiplied with a proportional gain and feed to the system.
What is frequency dead band in turbine control system?
it is range of frequency variation for which governor does not take any proportional corrective action.
Do semiconductor material have a very high resistance at room temperature?
No. As temperature increases, resistance of semiconductors decrease. This is because semiconductors have a small energy gap between their valence band and conduction band (in the order of 1 eV). Electrons must exist in the conduction band in order for the material to conduct but electrons exist in the valence band naturally. The electrons gain thermal energy for surroundings and jumps the energy gap from valence band to conduction band and hence, the SC material more readily conducts. As temperature increases, electrons can gain more thermal energy, more electrons can enter the conduction band and hence, resistance decreases.
Do Power is directly proportional to resistance or inversely proportional to resistance?
It is both proportional and inversely propertional to resistance however I am not exactly sure why which is why I am searching Google ATM for answers.
Is Power required to drive a centrifugal pump is directly proportional to diameter of the impellor?
yes....power is directly proportional to cube of dia.
What is Proportional Band?
In practice, the controller output is limited, either by its own limitations or by the limitations of the corresponding actuator. Let umax and umin denote the minimum and maximum output of the controller. The proportional band of the controller is then defined as:In the ideal case, a controller can have an unlimited output. The proportional band (PB) is then defined as:This definition of proportional band is often used instead of the controller gain. The value is expressed in percent (%).
Damping is proportional to?
1/sq. root of gain
Why gain increases in low frequency region in BJT?
Because Beta (current gain) in a transistor is inversely proportional to frequency. Hence it increases as frequency decreases. Also the ac voltage gain is directly proportional to Beta.
What is proportional control?
Proportional controllerA proportional controller is a type of a feed back controller where the difference between the measured output and the input (the desired output) is multiplied with a proportional gain and feed to the system.
Why is it a good idea for a band to do a cover?
It's a good idea for a band to do a cover because if the song is very popular with people it gain the band tends to gain more followers/fans.
Can you gain weight after lap band surgery?
It's possible.
What is frequency dead band in turbine control system?
it is range of frequency variation for which governor does not take any proportional corrective action.
What is a type of force in a stretched rubber band?
The force could be in Newtons or poundsforce. It will be proportional to the amount of stretch, up to the limit of elasticity.
Does the lap band surgery prevent weight gain?
Lap-band surgery is probably the most preffered way to lose weight out of most other surgery procedures. It does not prevent weight gain, but it does help you with weight loss.
How is a proportional and non-proportional relationship different?
Proportional is when it is proportional.
Is the elastic property of the rubber band a good example of Hooke's law explain?
Yes, it is, as long as you do not stretch it too much that it permanently deforms. Hooke's law states that extension is proportional to force, as is the elastic band.
If A is proportional to B square and B is proportional to C Square then A is proportional to?
A is proportional to C4.
