How do i do this ? ? ?
: Suppose you have collected the data shown below for the circuit in Figure 1.
Voltage is measured across the
resistor. Current is measured
through the resistor. The
exact value of the resistor is
100 Ω.
Figure 1.
DESCRIBE THE MEASURED QUANTITIES:
“x” Electric Current in Amperes .
“y” Voltage in Volts .

2 .083 A 8.2 V
3 .127 A 12.3 V
4 .162 A. 16.0 V
5 .200 A 21.0 V
EQUATION OF DATA (USING FORM y = mx + b): .
ACCEPTED VALUE FOR k: .

NEVER MIND I CANT Get it to post
@SMD^^
Unless you can help it, no one wants to see that.
So keep your dirty thoughts to yourself please.
Thank you

To analyze the data and answer the given questions, you need to follow these steps:
1. Observe the data provided in the table for "x" (Electric Current in Amperes) and "y" (Voltage in Volts) for different trials.
2. Calculate the value of k (k = y/x) for each trial by dividing the voltage (y) by the current (x).
3. Use the equation of a straight line, y = mx + b, to represent the relationship between "x" and "y". The goal is to find the slope (m) and the y-intercept (b).
4. To find the slope (m), calculate the average value of k by adding up all the k values and dividing it by the number of trials.
Average k = (k1 + k2 + k3 + k4 + k5) / 5
5. To find the y-intercept (b), you will need to find the value of "y" when "x" is zero. Look for the trial where the current "x" is closest to zero. For that particular trial, observe the corresponding value of "y". This value will become the y-intercept (b).
6. Determine the accepted value for k. This value is a theoretical or expected value obtained from prior knowledge or calculations.
7. Calculate the accuracy of the data by finding the percentage difference between the average value of k and the accepted value of k using the following formula:
Accuracy = (|average k - accepted k| / accepted k) x 100%
8. Determine the precision of the data by calculating the percentage difference between the highest and lowest values of k using the following formula:
Precision = (|highest k - lowest k| / lowest k) x 100%
By following these steps, you will be able to describe the measured quantities, calculate the equation of the data, find the accepted value for k, and determine the accuracy and precision of the data.
