A displacement transducer has the following specifications Linearity error ±0.1% of reading, Drift ±0.15%/C of reading, sensitiv
ity error ±0.25% of reading, excitation 10-25 V DC, output 0-5 V DC, range 0-5 cm. The output is to be indicated on a voltmeter with accuracy of ±0.15% of the reading and has a resolution of 10 µV. The system will be used at "room temperature" which can vary by as much as 5C. Estimate the design stage uncertainty in a 3.5 cm reading assuming 95% confidence. Read your book to learn more details about this.

Answer:
Part 1: It would be a straight line, current will be directly proportional to the voltage.
Part 2: The current would taper off and will have negligible increase after the voltage reaches a certain value. Graph attached.
Explanation:
For the first part, voltage and current have a linear relationship as dictated by the Ohm's law.
V=I*R
where V is the voltage, I is the current, and R is the resistance. As the Voltage increase, current is bound to increase too, given that the resistance remains constant.
In the second part, resistance is not constant. As an element heats up, it consumes more current because the free sea of electrons inside are moving more rapidly, disrupting the flow of charge. So, as the voltage increase, the current does increase, but so does the resistance. Leaving less room for the current to increase. This rise in temperature is shown in the graph attached, as current tapers.
Answer:
<em>Python code is as follows: </em>
********************************************************************************
#function to get number up to any number of decimal places
def toFixed(value, digits):
return "%.*f" % (digits, value)
print("Enter the price: ", end='', flush=True) #prompt for the input of price
price = float(input()) #taken input
totalCost = price + 0.05 * price #calculating cost
print("Total Cost after the sales tax of 5% is applied: " + toFixed(totalCost,2)) #print and output totalCost
