What is digital thermometer?
the special purpose digital voltmeter are devloped for measurement of temperatur. They are called as the digital thermometer .
Which equipment is most useful when measurin Barometer and voltmeter Light meter and barometer Voltmeter and thermometer Thermometer and light meter the two environmental changes mentioned above?
A thermometer and light meter are the most useful when measuring two environmental changes.
A cars speedometer measures?
The car's speedometer indicates the car's instantaneous speed. This is a big part of the reason that it's not called the car's accelerometer, thermometer, or voltmeter.
Some laboratory equipments?
Examples: analytical balance, thermometer, pH-meter, refractometer, spectrophotometer, microscope, hardness tester, viscosimeter, electronic titrator, voltmeter, etc.
Why is ascale use to measure weight?
Because measuring weight with a ruler, speedometer, Geiger counter, voltmeter, thermometer, or frequency counter is prohibitively difficult, and has been all but rejected by the technological community.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
Voltmeter in series?
No. Voltmeter in parallel. Ammeter in series.
