Aim
To use vernier calipers to measure small lengths, finding the least count and correcting for zero error.
Measure a bob, a beaker, a wire and a sheet with vernier callipers and a screw gauge, find the least count and correct the zero error, with a magnified window over each scale.
What you'll explore
- Vernier callipers Least count 0.1 mm.
- Screw gauge Least count 0.01 mm.
Who it's for
Class 11 physics, for CBSE, ICSE and State boards. It follows the practical in your textbook: least count, zero error.
