Which one of the following conditions is unfavorable for the use of an ohmeter?

An ohm-meter measures the resistance by applying a voltage across the component. The current flowing through the component is measured, and a little bit of Computation of the form R=V/I would give the resistance.  \n\nIf a voltage is already supplied, then the ohm-meter may read erroneously or may even get screw**.

Any temperature-sensing device whose resistance is a function of temperature is inherently nonohmic; i.e., does not display a constant resistance with varied current flow or varied applied voltage. This is due to the fact that current flow will cause the device to heat and do its job which is to change resistance. An NTC device could conceivably "run away" with a constant applied voltage; as current increases it heats up and its resistance goes down resulting in further current increase. Conversely, a PTC device could conceivably run away with a constant applied current; as it heats up its resistance increases resulting in a higher voltage drop across it, which produces more heating, etc. For this reason, when using a thermistor it is a good idea to measure its resistance with a very sensitive (low sensing voltage and current) ohmmeter to minimize spurious heat input.

Proper Voltage of Tolerance that a body can take is not harmful, but more than the tolerable can get body organs cooked.  \nElectricity never reamsin in the human body it just pass through.. for a brief millisecond...\n\n-- Hope this helps.. Goodluck =)

Under high heat or pressure, yes\nAt STP, no

Remember the equation v/i=r, Keep the voltage constant over all the areas. If the resistance goes up, then the current goes down.\nIf you have zero ohms, you have a short. IF you have infinite resistance, you have a break.  This seems general, but this is a great help for most of the electronics applications you will need. \nIf you want more you will need to give us more info.

Maybe you could use its electrical resistance. But it wouldn't be easy as I suspect the temp coeff of the resitance is small.

You guys are both right--good answers.  Junction temperature also can affect the voltage drop.

Hynton has it.  Just remember that you'll be restricted to x > 0 because of the original form of the problem.

during and distructive test, danger exists. knowlege of the equiptment and proceedures are a must. if the exact failure point is to be measured, then at yield the test should be slowed. It will also minimise flying samples.

I've worked with flowmeters for 20+ years and have never heard of this... what medium are you trying to measure?

You could use a resistor in series for the voltmeter and a shunt resistor in parallel with the ammeter.  You can also use a signal amplifier to transform the input signal to one that is within the range of the meter.  If it is a panel type meter, do not forget to change the scale behind the meter.\n\nJeffM

Also, when you say "design problems" it sounds like you're asking about the technical challenges or technical flaws. A technical challenge would be when the designers have to figure out how to design a particular circuit. A technical flaw would be an error in a multiplier that went unnoticed before production. \n\nOn the other hand you may be asking about architectural problems, which refers to problems with some aspect of the 8086 architecture, e.g. the segmented memory architecture used to be a big limitation that the Motorola 68000 did not have.

Flux capacity...hmmm now that's a good one.\n\nI agree, I think someone is pulling your leg.\n\nThe only flux terminolgy I'm aware of is soldering flux, but it's not even measured, much less as a capacity measurement.

Design 1 because it requires the least energy meaning the least risk of getting electrocuted when using a high voltage engine.The users safety must be considered too.

A general rule of thumb I have heard in engineering is "the fewer moving parts the more reliable" (another conflicting rule is "if it ain't broke, it doesn't have enough features yet").\n\nI would say it depends on the application.  I know hard-drives inside computers or MP3 players are very sensitive mechanical components.  Then again, electrical hardware is prone to overheating.

One does not need studies to know that turning something OFF uses less elecricity than something that is ON. Just like a car that is not running uses less gas than a car that is running..whoooaah
