Question

A:

What is the smallest increment on the voltmeter?

B:
What is the uncertainty?

Answer 1

#A

• total lines segment=10
• Segment=1-100

Smallest increment=100/10=10V

#B

uncertainty

• 10/20
• 0.5V

Answer 2

The voltmeter on the left has an analogue scale. The smallest scale division is 1 volt. The uncertainty from reading this scale is ± 0.5 volts.
