how many significant figures should be used to calculate uncertainty?

 

[Talha]

1 significant figure nd decimal places of both the value nd uncertainity must be same

Question 2 part b, how do you find out the absuloute values? Don't you just divide the maximum of V with the minimum of I? And subtract it from the value you get of V/I?

divide the given value of V0 by I0 and separately treat the uncertainties. For eg. Xc for the first row is 5/0.0015.

If we use signal generator , do we have to use alternating power supply ?
