Which mode is use in digital multimeter for testing of diode?
A: For a digital meter to test a diode it must have a scale for resistance for it to work, If not a 1.25 v cell with series limiting resistor will work. If you measure across the diode the reading should be .7 volts reverse the cell polarity then the diode voltage should be 1.25 v .7v is forward voltage 1.25 is reverse voltage.
Latitude and longitude lines help geographers identify .?
Location. They are intersections like a street corner, only on a global scale.
What is a streak plate on the mohs scale?
A streak plate on the Mohs scale is a piece of unglazed porcelain used to determine the color of a mineral in powdered form. By rubbing the mineral against the streak plate, it leaves a streak that can be compared to the standard colors on the scale to identify the mineral.
What are the steps in construction of semantic differential scale?
Identify the concept you want to measure. Choose opposing adjectives that represent the extremes of the construct. Assign a numerical scale (typically 5 to 7 points) with anchor points for each pair of adjectives. Test the scale for reliability and validity before using it in research.
Moh's Scale is used to determine this. streak hardness acid reaction luster?
Moh's Scale is used to determine the hardness of minerals. It ranks ten minerals from 1 (talc) to 10 (diamond), allowing comparison of their resistance to scratching. This scale helps identify minerals based on their hardness relative to one another.
How do you identify the polarity of a diode when the tester is on resistance scale?
ln reverse biase high resistance and in forward biase very low resistance
What is the geomagnetic reversal time scale?
The geomagnetic reversal time scale has patterns of polarity. It is the pattern of alternating and reserved polarity in rocks.

A: For a digital meter to test a diode it must have a scale for resistance for it to work, If not a 1.25 v cell with series limiting resistor will work. If you measure across the diode the reading should be .7 volts reverse the cell polarity then the diode voltage should be 1.25 v .7v is forward voltage 1.25 is reverse voltage.
How do you identify for a shorted and an a opened transistor?
This can be quickly done with a multimeter in ohms or diode scale. Test EB & CB junctions as you would ordinary diodes and test CE for leakage both ways (there should be none).
What is the name of the scale we use to identify minerals?
The scale used to identify minerals is called the Mohs scale of mineral hardness. It ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
How do you use a diode as temperature sensor?
The voltage across a Silicon Diode junction varies 0.00011 volts per degree Kelvin. Connect the diode to a high gain amplifier and the output of the amplifier to a DVM using an appopriate voltage scale.
Scientists used the pattern of alternating normal and reversed polarity in rocks to create the geomagnetic?
time scale
How to take a main scale reading and vernier scale reading?
To take a main scale reading, identify the whole number on the main scale that is to the left of the zero mark on the vernier scale. Then, identify the vernier scale division that aligns closely with a division on the main scale. Add the main scale reading and the vernier scale reading together to get the final measurement.
What is the highest range of voltage that can be detected by a tester?
The highest voltage scale on a hand held multimeter is 5000 volts.
What is analog tester?
simply means the tester's measurement is displayed in an analog way (not digital) For example: a moving needle that points to a scale a clock with hands is ANALOG a clock that displays the time like this (11:55pm) is DIGITAL
What would you use the Mohs scale for hardness for?
to identify a mineral
How do you identify a mineral or crystal?
You can use hardness(Moh's Hardness Scale), luster, shape, and fracture to identify quartz.
