What kind of disorder is diabetes type 2?
Diabetes type 2 is a metabolic disorder, caused by insulin resistance in the cells of the body, combined with insufficient insulin formation. It is quite a separate disorder than diabetes type 1, which is caused by an autoimmune reaction that destroys the insulin-producing cells in the pancreas.
What is resistance of stator winding of induction motor?
Resistance of stator winding is the resistance of the copper conductors being used for building the windings of three separate phases, i.e. R-Y-B. These windings are marked like U1-U2, V1-V2 & W1-W2 at the motor terminals (6 nos.) for the three phases, i.e. R-Y-B respectively. We have simply to measure the resistance of each winding by using a multimeter by connecting the terminals (2 no.) to U1 & U2 and so on. The resistance should be in ohms not milliamps [amps is form of measuring current not resistance] milliamps to microamps in case of large motors, it may be in amps in case of small sized motors. But resistance of each winding should be nearly same to each other. This shows the electrical balance among windings & also proves the healthiness of the winding.
Why you measure resistivity and not resistance in four probe method?
Resistivity is a constant for a material as opposed to resistance which is dependent on size considerations. This is analogous to specific heat capacity and heat capacity. It can be said that resistivity is more useful for comparison because other factors (size) have been accounted for.In the case of using the four-probe method to measure the thickness of a thin film:ρ = (V/I) x (thickness of film) x (correction factor)We measure the current and voltage using the four-probe method, from which we can get the resistance between the probes. Knowing the resistivity, which is constant for the material and can be obtained from sources such as books, will enable us to relate the resistance to the dimensions of the film.
Combined sewage pipes or separate sewage pipes?
Depends on local codes and if separate drainage is available
What happens to resistance when the conductor diameter is increased?
Simply Stated: As electrons move across a wire, they constantly collide with atoms making up a wire. These collisions impede the flow of electrons and are what cause the wire to have resistance. Thus, if the diameter of the wire were larger, it would only make sense that the electrons don't collide as much, therefore creating less resistance due to a larger wire. This is all in accordance to Ohm's law. The resistance is the ratio of the voltage difference across an object to the current that passes through the object due to the existence of the voltage difference. If the object is made of a material that obeys Ohm's Law, then this ratio is constant no matter what the voltage difference is. Consider a copper wire that passes some amount of current, say 1 A, when a voltage difference of 1 V is applied between the ends of the wire. Now consider an identical but separate wire connected across that same 1V potential difference. You would expect that it would also conduct 1 A. Now think of joining those two wires together side by side into one, thicker wire. It is reasonable to expect that this wire should carry 2 A of current if the potential difference across the wires is still 1 V. Thus, the new, thicker wire will have a reduced resistance of 1/2 Ohm compared to the original wire with its resistance of 1 Ohm. Basically, a thicker wire creates additional paths for current to flow through the wire.
When two lengths of the same uniform wire are connected together the effective resistance is the sum of the separate resistances is this correct?
Yes. Resistances in series add up. RSERIES = Summation1toN RN
How would it be connected so that the effectiveness of the resistance is the sum of the separate resistances?
In series.
How do you separate methanol from surfactants?
There are a number of methods that can be used to separate methanol from surfactants. The most effective method is extraction of the cationic surfactants by contracting the mixture with water.
Is friction resistance and air resistance the same?
No, Air resistance can be considered as a type of friction however, friction itself is considered to be the a force which opposes motion between two surfaces/substances. For example, A train travelling with a driving force of 500N Has 50N of air resistance acting on it and 75N of friction from the rails. They are considered to be separate.
What are the limitations of ohms law?
It requires the ability to multiply and divide. It requires the ability to mentally separate voltage from current and to understand resistance and when to add resistance for series circuits and worse identify and calculate parallel loads.
Why separate resistancesvariable resistances or resistance materials are used in electric circuits neglecting the resistance of the connecting wirescopper wiresin calculations?
The resistance of the connecting wires in most cases would be negligible compared to that of any component listed as a resistor and again, in most cases, would have little effect on calculations.
How is it that the insulin stops working and or doesn't produce enough?
This question consists of two separate sections. The insulin made in a person's body may become less effective if a phenomenon known as insulin resistance develops. Genetic and environmental factors interact to make insulin less effective at the level of the cell membrane, so that excess fats and sugars in the blood are not used appropriately. The body's first response to insulin resistance is to produce more insulin in specialized areas of the pancreas known as beta cells. Over time, beta cells become less able to produce insulin, and blood sugars may continue to rise.
How can you separate salt from a solution of salt in water?
Distillation would be the most effective method. In this manner, you can obtain both the distillate and the residue.
What would be the most effective strategy for gathering details about two subjects you want to compare?
The most effective strategy would be to interview these two subjects on separate occasions. Find out all you possibly can about them and then compile your information to compare them.
Does Virginia Law allow spouses to have separate Insurance policies?
Spouses are allowed to carry separate insurance policies, as there are no laws stating otherwise. However, it is generally more cost effective for spouses to carry one together.
What is the equivalent resistance if six 18 kOhm resistors are connected in 1. series 2. parallel as was asked by Mackey90 on 8 December 2008?
6 separate 18kOhm resistors wired in series make a total resistance of:18k+18k+18k+18k+18k+18k which is 108 kOhm.6 separate 18kOhm resistors wired in parallel make a total resistance of:1/[(1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k)] which is 3 kOhm.
