    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.

    The output voltage is loving by the voltage divider equation: 21 R1+R2 believe the voltage beginning produces a voltage of V,-5V with an faultlessness of ±10mV, the resistor R1 has a suppositious estimate of 1k(2 with a tolerance of ±5%, and we estimate the voltage V2 with our voltmeter to be 3.5V and we apprehend the hallucination in our voltmeter lection to be ±20mV. If we interpretation the overhead voltage divider equation to estimate the estimate of the resistor, R2, comprise the aftercited derivations in your prelab: (1) What is the estimated estimate of R2? (2) What skin of hallucination should we wait-for in our estimated estimate of R? That is, what is the acme and stint equality we could wait-for to be unpremeditated by?
