A 100:1 voltage divider is required in order to create a 200vdc full scale range for a basic measurement system with 2 vdc full scale input. The voltage divider is illustrated in figure 1. Figure 1 The input voltage range of V₁ expected is 1 vdc to 200vdc when using this divider. The nominal resistor values(at 25 °C) are R₁ = 990 kohm, R₂ = 10 kohm. The resistor specifications are: nominal tolerance: ±0.2% temperature coefficient: ±100 ppm/"C max voltage coefficient: -25ppm/volt (typical) a. What is the maximum variation in the voltage transfer ratio V₂/V₂ due only to the initial tolerance? Give the minimum and maximum values. b. What is the maximum variation in the voltage transfer ratio V₂/V₁ over the temperature range of 0°C -50 °C, relative to the initial 25 °C value, due solely to the temperature variation? Give the minimum and maximum values. c. What is the maximum variation in the voltage transfer ratio V₂/V, due solely to V₂ variation over the range 1 vdc -200 vdc? Give the minimum and maximum values. d. What is the maximum variation in the voltage transfer ratio V₂/V, due to any possible combination of voltage input, initial tolerance, and temperature? Give the minimum and maximum values. A 100:1 voltage divider is required in order to create a 200vdc full scale range for a basic measurement system with 2 vdc full scale input.
