Imagine you came to the lab and found a resistor with the color code Blue, Red, Brown, Gold. What is the resistance of this resistor (with uncertainty)? (HINT: Uncertainties should have only one significant digit and should always be rounded up)
(620 ± 40) Ω
(620 ± 62) Ω
(620 ± 31) Ω
(602 ± 10) Ω
In lab, you measured the resistance of a resistor with a digital multimeter to be 0.997 kΩ. What is the uncertainty in this measurement?
0.05 kΩ
0.0005 kΩ
0.001 kΩ
0.1 kΩ
