Question

If the value of resistance is 10.845 ohms and the value of current is 3.23 amperes, the potential difference is 35.02935 volts. Its value in significant number would be

• A. 35 V
• B. 35.0 V
• C. 35.03 V
• D. 35.025 V

Answer 1

Answer: (B)

35.0 V

Answer 2

Value of current (3.23 A) has minimum significant figure (3) so the value of potential difference $V ( = I R )$ have only 3 significant figure. Hence its value be 35.0 V.
