1. The problem statement, all variables and given/known data What are the percentage errors for lengths measured with meter rulers and potential differences measured with voltmeters? I have a question asking me which of the two measurements can be measured more accurately, based on which one's percentage error is lower. 2. Relevant equations 3. The attempt at a solution Is it done this way: For length, % error = 1/1000 *100 For p.d., % error = 1/10 *100 ??? Please clarify, thanks.
