In Connect, the standard answer tolerance for numeric questions is 2%. To satisfy this 2% tolerance, you should use at least three significant digits when entering your answers into Connect. It is also important never to truncate or to round intermediate steps, variables, and symbols (like π) unless otherwise specified in the problem statement. Please consider this rule in the following situation: According to the Ohm’s law, the potential difference across the conductor (ΔV) is equivalent to the product of the current through the conductor and the total resistance of the conductor. Therefore, current can be expressed as voltage (potential difference) divided by resistance (I= ΔV/R). Based on this equation, a student is asked to find the current through a conductor if the voltage equals 155 V and the resistance is 69 Ohms. The student calculates this problem to 9 digits to be 2.24637681 A. The answer with two significant digits is closer to the 2% tolerance range, but is just below the lower end of the tolerance (2.20144927 A). Therefore, In this case, it would not be graded as correct. 1. What is the current to three significant digits? 2. What is the current to four significant digits?3. Do both of these values fall within the 2% tolerance?
