How do you find least count of voltmeter and ammeter?
Least count of voltmeter is the value of one division on the scale. Formula is: Least count = Range/No. of divisions For example, if a voltmeter can measure from 0 to 40 V, and it has 100 divisions in total on the scale, then its least count is 40/100 = 0.4V
What is the least count of ammeter?
The least count of an ammeter refers to the smallest change in current that can be measured by the device. It is typically determined by the scale divisions on the display of the ammeter. For example, if an ammeter has a least count of 0.1 A, it means that it can detect changes in current as small as 0.1 ampere.
What is the smallest main scale division in a vernier scale with 50 divisions?
The smallest main scale division in a vernier scale with 50 divisions is 1/50th of the main scale division. This is because each division on the vernier scale corresponds to 1/50th of a main scale division, allowing for more precise measurements to be made.
What is the least count of an ammeter?
The least count of an ammeter is the smallest value of current that can be measured by the instrument. It is typically determined by the scale divisions marked on the device and is an important factor in accurately reading and interpreting the measured current values.
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.

How is a voltmeter visually different from an ammeter?
They can both be the same superficial size and have the same visual appearance as a "meter" but a voltmeter has its scale marked out in volts and an ammeter has its scale marked out in amps.

What is the smallest main scale division in a vernier scale with 50 divisions?
The smallest main scale division in a vernier scale with 50 divisions is 1/50th of the main scale division. This is because each division on the vernier scale corresponds to 1/50th of a main scale division, allowing for more precise measurements to be made.
How do you Design and draw a circuit of multiple scale ammeter?
To design a circuit with multiple scale ammeters, you can use a shunt resistor method. Connect a low-resistance shunt in parallel with the ammeter, allowing different current paths depending on the desired range. For each scale, use a different shunt resistor value calculated based on Ohm's law to ensure the ammeter reads appropriately for varying ranges. Finally, label each scale clearly for user reference.
What is ammeter sensitivity?
Ammeter sensitivity can be determined by a change of scale for the ammeter which would introduce higher or lower resistance values depending on the reading required. A higher sensitivity for lower values of ampacity would require higher resistance in the measuring circuitry. Use Ohm's law to verify.
What is the smallest main scale division in a vernier scale with 25 divisions?
In a vernier scale with 25 divisions, the smallest main scale division is typically determined by the relationship between the main scale and the vernier scale. If the vernier scale is designed to provide a finer measurement, it often allows for a reading that is a fraction of the main scale division. For example, if the main scale has divisions of 1 mm, the smallest division on the vernier scale would allow for readings accurate to 0.04 mm (1 mm / 25), giving a finer resolution than the main scale alone.

What does the smallest division on the main scale of the micrometer gauge correspond to?
The smallest division on the main scale of a micrometer gauge typically corresponds to 0.5 mm or 0.025 inches. This is the precision at which the main scale can be read.
