if there are 20 divisions between 0 to0.5 least count is 0.5/20
To find the least count of a micrometer in the imperial system, first convert the micrometer value to inches. Then, divide 1 inch by the number of divisions on the micrometer scale. This will give you the least count of the micrometer in the imperial system.
To find the sensitivity of a vernier caliper, measure the least count of the caliper (typically 0.02 mm) by dividing the smallest division on the main scale by the number of divisions on the vernier scale. For a micrometer, measure the least count (typically 0.01 mm) by dividing the smallest division on the main scale by the number of divisions on the thimble scale. Sensitivity indicates the smallest change in measurement that can be detected by the instrument.
To find the frequency of a sound wave, you can count the number of complete cycles of the wave that occur in one second. This is typically measured in hertz (Hz).
To find the frequency of all words in a text, you can tokenize the text into individual words, convert them to lowercase to ensure case insensitivity, then count the occurrences of each word using a data structure like a dictionary in Python. Finally, you can iterate over the list of words and increment the count for each word in the dictionary.
A pulse or heart rate can be taken from the radial artery on your wrist to count heartbeats in one minute. Place your index and middle fingers over the inner side of the wrist, below the base of the thumb, and count the number of heartbeats you feel within a 60-second interval. This method provides a convenient and commonly used way to measure heart rate quickly and easily.
Connect ammeter in series and voltmeter in parallel to the circuit
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
To find the least count of an instrument or measuring device, divide the smallest measurement unit by the total number of divisions on the scale. The least count represents the smallest increment that can be measured or displayed by the instrument.
Generally electronics meters may be ammeter Or Voltmeter. So for measuring the components Value We use a small small circuits . Ex :- to measuring the value of Resistor we supply voltage acroo it & add a Ammeter to measuring the Current thats why we can find value of resistance using Ohm's Law.
I am going to assume that you mean low "resistance" in an open circuit test and are performing this with a multimeter. An ammeter works by place a very small amount of resistance in series with a circuit and then measuring the Voltage drop across the resistance. The Voltage is directly proportional to the current as given in ohms law: E = I x R If you are measuring the resistance through the ammeter it will have a very low resistance and impedance.
LC= S over N
If lights randomly go off, there is likely a wiring issue. Using a voltmeter or ammeter may find a break in the wire or a short circuit of some kind. A fuse could also be loose.
The least count of an odometer is determined by the smallest division or increment that the odometer can measure. To find it, look at the smallest digit on the odometer scale; for example, if the odometer's smallest division is 0.01 km, then its least count is 0.01 km. This value indicates the minimum distance the odometer can accurately record.
By using an Ammeter in series
To find the least count of a micrometer in the imperial system, first convert the micrometer value to inches. Then, divide 1 inch by the number of divisions on the micrometer scale. This will give you the least count of the micrometer in the imperial system.
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
Power dissipated by the resistor = I^2 * R or V^2 / R, where R = its resistance value, I = the current in the resistor, and V = the voltage drop across the two terminals of the resistor. You need to measure or find the information of either I (using an ammeter) or V (a voltmeter).
