Physics And Measurement Question 277
Question: The value of resistance is $ 10.845\Omega $ and the value of current is 3.23 A. The potential difference is 35.02935 volt. Its value in significant number would be
Options:
A) 35V
B) 35.0V
C) 35.03V
D) 35.029V
Show Answer
Answer:
Correct Answer: B
Solution:
[b] The significant number in the potential, $ V=iR $ ;
should be the minimum of either
or R. So corresponding to $ i=3.23A $ , we have only three significant numbers in $ F=35.02935V $ .
Thus the result is $ V=35.0V. $
