hiya, I have no idea how to answer questions in this topic.....
the task is to give the absolute uncertainty (including units), the heading you would put in the results table and the number of decimal places you would give in the results table for:
(1) voltage, using a multimeter reading in volts to 3dp
(2) current, using a multimeter, reading in amps to 3dp, but the last digit fluctuates.
(3) a length measured using a metre rule that has mm marks
(4) a time, where you manually operate a stopwatch that reads to the nearest hundredth of a second.
please help x
