    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 attached by the voltage divider equation: 21 R1+R2 prepresuppose the voltage fountain produces a voltage of V,-5V with an faultlessness of ±10mV, the resistor R1 has a formal appraise of 1k(2 with a tolerance of ±5%, and we rate the voltage V2 with our voltmeter to be 3.5V and we apprehend the blunder in our voltmeter lection to be ±20mV. If we explanation the overhead voltage divider equation to apportion the appraise of the resistor, R2, comprise the subjoined derivations in your prelab: (1) What is the apportiond appraise of R2? (2) What peel of blunder should we await in our apportiond appraise of R? That is, what is the climax and reserve whole we could await to be unstudied by?
