Precision Measures in Measurement Devices

The video tutorial explains how to determine the precision measure of analog scales. It covers examples using a meter stick, graduated cylinder, thermometer, spring scales, and voltmeters. The precision measure is defined as half the space between divisions on the scale. The tutorial also discusses non-linear scales and how precision varies depending on the scale's divisions.

What is the precision measure of an analog scale?

• Twice the space between divisions

• The space of one division

• Half the space between divisions

• The full space between divisions

If a meter stick has 10 divisions in 10 mm, what is the precision measure?

• 5 mm

• 2 mm

• 0.5 mm

• 1 mm

In a graduated cylinder with 10 divisions in 10 ml, what is the precision measure?

• 5 ml

• 1 ml

• 2 ml

• 0.5 ml

How is the precision measure determined for a thermometer with 10 divisions in a 10° span?

• 5 degrees

• 2 degrees

• 0.5 degree

• 1 degree

For a graduated cylinder with 10 divisions in 5 ml, what is the precision measure?

• 2 ml

• 0.25 ml

• 0.5 ml

• 1 ml

What is the precision measure of a spring scale with 10 divisions in 100 g?

• 1 g

• 2 g

• 5 g

• 10 g

If a spring scale has 25 divisions in 50 g, what is the precision measure?

• 5 g

• 2 g

• 1 g

• 0.5 g

How does the precision measure vary in a device with multiple scales?

• It is always the smallest division

• It is the average of all scales

• It depends on the scale being used

• It remains constant across all scales

In a non-linear scale, how does the precision measure change?

• It is always the largest division

• It varies depending on the position on the scale

• It is constant throughout

• It is the same as the smallest division

What is the precision measure at the end of a scale with one division between 4,000 and 5,000?

• 2,500 units

• 1,000 units

• 250 units

• 500 units
