Answer
3
Work Step by Step
Apply the rules on page 162 of the book to find the significant digits (the accuracy) of the measurement $36\bar{0}0$ V.
We use rule #1: all non-zero digits are significant. Thus, "3,6" are significant.
We use rule #3: the tagged zero digit is significant. Thus, we have a tagged zero which is significant.
Thus, there are 3 significant digits.
