What is dielectric absorption ratio?
This is a test usually used when performing a insulation resistance on a transformer. This test (result) can be optained by deviding the 30 sec reading into the 60 sec reading. This test recognizes the fact that "good" insulation will show a gradually increasing IR after the test voltage is applied.
What is the difference between power consumption and power dissipation?
A: POWER consumption is total power usage power dissipation is wasted power in the form of heat, IR drop and so on.
How test resistances?
we can measure the resistance if we know the voltage and current passing through a line (V=IR)AnswerYou can measure its approximate resistance using an ohmmeter, but ohmmeters aren't particularly accurate. A better way would be to use a Wheatstone Bridge, which is highly accurate.
What is the relation between voltage and current?
Voltage and current are two different things. Voltage is the electric potential difference between two points. Expressed in volts, it is also joules per coulomb. Current is the charge flow past a point. Expressed in amperes, it is also coulombs per second. You can relate voltage and current using Ohm's Law, which states that voltage is equal to current times resistance. Resistance is, therefore, equal to voltage divided by current. Using base units, resistance is equal to joules per coulomb divided by coulombs per second, which simplifies to joule-seconds per coulomb squared. That is a difficult unit to write, so we just use ohms as the unit.
What is IR Thermometers?
A IR thermometer or Pyrometer is used where it is not possible to measure temperature with contact, IE very hot or very cold temperatures or where the object is a distance away. Infrared is in the 10-6 to 10-4 Meter band, this is called the thermal radiation band. It is between the microwave band and the visible light band. An IR thermometer, transmit a predefined IR frequency signal to the object under measurement, if the IR generated by that object itself is of a lower frequency than the received IR, that frequency is subtracted from the received frequency and that IR signal is then reflected back to the IR thermometer, this received signal is then used by the build in electronics of the thermometer to calculate the temperature of the object under measurement. Some uses: * Detecting clouds for remote telescope operation * Checking mechanical equipment or electrical circuit breaker boxes or outlets for hot spots * Checking heater or oven temperature, for calibration and control purposes * Detecting hot spots / performing diagnostics in electrical circuit board manufacturing * Checking for hot spots in fire fighting situations * Monitoring materials in process of heating and cooling, for research and development or manufacturing quality control situations
What is difference between IR and FT IR?
nothing
What is the difference between NAIR and FT-IR instruments?
nothing
IS there a difference between Oxycontin hcl 5mg and oxycodone ir 5mg?
Yes Oxycontin hydrochloride is a time released tablet and oxycodone ir is an instant release tablet.
What is the difference between pir movement sensor and ir sensor?
Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.
What is the difference between vámanos and vamos?
Vámanos is the command form of the verb ir and means 'let's go!"Vamos is the 1st person plural form of the verb ir and means "We go".
What is the maximum distance reached using IR transmission?
Between 2 standard IR devices it is 1 meter. Between 2 low power IR devices it is 0.3 meter Between a standard and a low power IR device it is 0.2 meter
What is the minimum value of Ir test in 11kv cables?
4444
What is the difference between infrared (IR) and thermal imaging technology?
Infrared (IR) technology detects infrared radiation emitted by objects, while thermal imaging technology captures and displays the temperature variations of objects in a visual format.
What is the difference between IR and FT IR instruments?
A standard IR runs a single spectrum. An FT-IR uses an interferometer and makes several scans and then uses Fourier Transforms to convert the interferogram into an infrared spectrum.
What is the difference between HRM and IR?
hr is the overall management of all resources including workers, staff, executives, top management and even suppliers and customers. where as ir is relations between actual work force and management of the organization and also deals with collective bargaining and industrial conflicts
What is the difference between IR-1 and IR-6 immigration classifications?
IR1 for spouse who gets green card through consulate processing outside the US, IR6 for spouse who get green card through Adjustment of Status inside the US.
Difference between monetary base and money supply?
MB=CU+DEP (Currency +Deposits) MS=CU+DEP+IR (Currency + Deposits+International Reserves)
