Unformatted text preview: 1 Class project Name: ID: 1. You are given a volt meter with internal resistance greater than 99 k (1 k = 1000 ) and an ampere meter with internal resistance smaller than 0.01 . The voltage and current you read from these two meters carry enough significant digits for the problem you need to answer. You are also given a battery with emf 9.00 V and internal resistance 5 . With these three tools, (a) if you connect a circuit in the diagram shown in figure 1, what is the smallest resistance you can measure with a precision better than 1%? (b) if you connect a circuit in the diagram shown in figure s, what is the largest resistance you can measure with a precision better than 1%? (c) if you have a resistor with a resistance outside of the range you get from (a) and (b), discuss what connection you have to choose in order to achieve a measurement precision better than 1%? Please select two and only two questions out of the three questions. Write clearly your answers to the questions you Please select two and only two questions out of the three questions....
