Measuring Instruments (precision)
Easyphysics
Which instrument generally offers highest precision for small lengths?
Select the correct option:
Solution
Incorrect! Answer:
Screw gauge
- Precision comparison: Precision is limited by the instrument's least count (smallest graduation).
- Typical Least Counts:
- Meter Scale: 1 mm (0.1 cm)
- Vernier Caliper: 0.1 mm (0.01 cm)
- Screw Gauge: 0.01 mm (0.001 cm)
- Analysis: The Screw Gauge has the smallest least count, meaning it can distinguish between much smaller variations in length.
- Conclusion: Therefore, it offers the highest precision for measuring thin wires or plates.
