What is role of rheostat?
A rheostat is a resistor with variable resistance.There are many type of rheostat,involved of a rotary-type rheostat and a sliding rheostst.I dunn know much about the rotary-type rheostat but I can tell u how does a sliding rheostat work. A sliding rheostst consists of a coil resistance wire wound on a tube and a sliding contact.The sliding contact be moved on the metal bar.Consider of the length of the resistance wire which let electric current through increases,the reistance would be higher and decrease the elctric current.Thus by moving the sliding contact,we can adjust the size of electric current.It's ofter used as a dimmer or to adjustl the voluime of the radio. If you are interested in the rotary-type rheostat,try to find it by yourself!
How do you find the voltage at a point in a circuit with respect to a negative voltage?
First of all, 'voltage' means potential difference -and you cannot have a potential difference 'at a point'. Similarly, you cannot have a 'negative' potential difference, so it doesn't make sense to talk about a 'negative voltage'.Your question, therefore, should read: 'How do you find the potential at a point in a circuit with respect to a negative potential?'The answer is that you simply connect a voltmeter between the two points. The reading will give you the value of the potential. If it reads upscale, then it'll be positive; if it reads downscale, then it will be negative (i.e. even more negative tan the reference potential).
What could be the tendencies for the voltmeter if the voltages to be measured exceed the range?
You'd potentially damage the meter. Whether you do or not is immaterial; if the meter cannot measure the range of voltages you are expecting, it will not give accurate readings over that voltage range, thus you should not use it. Buy a different meter that will measure over that voltage range, or use a voltage divider circuit to get a lower voltage at a certain ratio of what is actually in the circuit (this may be difficult to do, or very simple depending on the circuit tested - the key is you do not want to load the circuit with the voltage divider network).
How much does a master plumber charge?
I cannot speak for all the other master plumbers but I charge normally $2,000 - $3,000 per day for my services for 7 hrs
Why calculate 22kv in mva?
A kilovolt (kV, not 'kv') is the SI unit for potential and potential difference (voltage), whereas the kilovolt ampere (kV.A, not'kva') is the unit for apparent power. These are quite different quantities, so you cannot change one to another -if that is what you are asking.

How do you find remainders in a division problem?
The remainder is the amount that cannot be divided into the equation, in other words, the leftovers. Example: 7 / 2 = 3 So now to figure out the remainder we multiply the divider by the answer. [in other words: 7 / (divider) = (answer)] [divider * answer] 2 * 3 = 6 So now to calculate the remainder we subtract this new answer by the number we started out with, in this case 7. 7 - 6 = 1 So the remainder is 1 [3 remainder 1]
Can 12 be divided by 0?
Undefined: You cannot divide by zero
What do they normally wear?
Your question cannot be answered unless you tell us in the question who "they" are.
Can sitting down give you breast cancer?
No it cannot. It normally runs in the family
Can you put a 49cc head on a 33cc crankcase?
Normally you cannot do this without modifications.
What is hipatic lipidosis?
This is when the liver becomes filled with fat and cannot function normally.
What can't you eat when your period is on?
There are no foods that you cannot eat. You may eat as you normally do
What do people in Italy think when they die?
Normally, one cannot think anymore when he dies.
What do you call someone who sees things someone else cannot normally see?
Crazy.
Why you cannot receive email?
I cannot receive my emails. I normally get 50 to 60 a day and now it shows that I have none. How do I see what there is waiting and how do I receive them?
If you ask a girl out and she says you are nice but she cannot be intimate with you what does it mean?
It means that while she sees you as a potential friend, she does not see you as a potential lover or mate.
