Why the zero of the ohmmeter scale is usually at the right end of the scale and reading increase towards the left?
Because the meter is actually measuring the current through the resistor, and the two quantities ... current and resistance ... are inversely proportional. So when the meter measures more current, it has to read less resistance, whereas higher resistance will result in less current. So the numbers for resistance have to be printed "backwards" on the meter scale.
What scale of resistance does a megohm meter measure?
Mega = million Megaohm = 1000000 Ohms
Is a voltmeter a linear scale?
This is because the resistance is measured by applying a fixed voltage to the resistor and measuring the current. Since I = V/R, the current/resistance relation is non-linear.
If you want to measure a current greater than the full scale deflection of the constructed ammeter in this case should the resistance in parallel with the galvanometer be increased or decreased?
A: the resistance should be decreased to 1/2 its value for half scale reading or use any ratio [ decrease] to obtain a correct reading.
An analog multi meter is quoted as having an accuracy of 1 k ohms and volt if it is set for FSD of 100v what is its loading resistance?
I think you mean the meter is rated at 1K ohms per volt. It means that with a series resistance designed to give FSD at any required voltage, the total series resistance must be 1000 ohms per volt (100K ohms for 100volts) . This is because 1K ohms per volt is just another way of saying that the full scale reading occurs at 1mA current. In that case a full scale deflection for 100 volts applied, 1mA is obtained with a total resistance (meter + added resistance) of 100 kOhms which is your loading resistance.
What is the resistance scale on an analog multimeter often termed?
Resistance is measured in ohms, so some refer to the resistance scale as the ohms scale.
What is the H-R scale?
The HR scale stands for Health Resistance
What is unit of abrasion resistance?
Mohs scale
If a multimeter reads zero on the ohm scale is this high or low resistance?
zero is low resistance
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 scale compares resistance of the surfaces of minerals to scratching?
The Mohs scale of mineral hardness measures the scratchability of minerals.
