    The output voltage is given by the voltage divider equation: 21 R1+R2 suppose the voltage source produces a voltage of V,-5V with an accuracy of ±10mV, the resistor R1 has a nominal value of 1k(2 with a tolerance of ±5%, and we measure the voltage V2 with our voltmeter to be 3.5V and we know the error in our voltmeter reading to be ±20mV. If we use the above voltage divider equation to calculate the value of the resistor, R2, include the following derivations in your prelab: (1) What is the calculated value of R2? (2) What kind of error should we expect in our calculated value of R? That is, what is the maximum and minimum amount we could expect to be off by?
    The output voltage is given by the voltage divider equation: V_2 = V_1 R_2/R_1 + R_2. Suppose the voltage source produces a voltage of V_1 = 5V with an accuracy of plusminus 10mV, the resistor R_1 has a nominal value of 1k ohm with a tolerance of plusminus 5%, and we measure the voltage V_2 with our voltmeter to be 3.5V and we know the error in our voltmeter reading to be plusminus 20mV. If we use the above voltage divider equation to calculate the value of the resistor, R_2, include the following derivations in your prelab: What is the calculated value of R_2? What kind of error should we expect in our calculated value of R? That is, what is the maximum and minimum amount we could expect to be off by?

    The output voltage is ardent by the voltage divider equation: 21 R1+R2 fancy the voltage cacorrection produces a voltage of V,-5V with an correctness of ±10mV, the resistor R1 has a ostensible rate of 1k(2 with a tolerance of ±5%, and we prize the voltage V2 with our voltmeter to be 3.5V and we apprehend the hallucination in our voltmeter balbutiation to be ±20mV. If we correction the over voltage divider equation to count the rate of the resistor, R2, comprise the subjoined derivations in your prelab: (1) What is the countd rate of R2? (2) What husk of hallucination should we wait-for in our countd rate of R? That is, what is the completion and minimum total we could wait-for to be unpremeditated by?
