A student measured an AC current of 0.152 Amps using a Fluke 8000A meter. Calculate the meter uncertainty of the current measurement in Amps.
Homework Answers
For ac current Fluke 8000A multimeter in 10A current range and 45Hz to 3 kHz frequency range has accuracy of +1% to -1% . So here meter uncertainity will be 0.00152 Amps.

2) Another student measured the period of a simple pendulum using a stopwatch. However, instead of measuring a single period, he waited for 10 periods to elapse before stopping the stopwatch. He obtained the time t = 19.40 s for ten oscillations. Report the period and its uncertainty in an appropriate format (assuming that the absolute uncertainty in the time measurement is still the same, i.e. 8t = 0.2 s). Calculate the fractional uncertainty in the period measurement.
