Chapter 11, Problem 1ICA

Jouleʼs first law relates the heat generated to current flowing in a conductor. It is named after James Prescott Joule, the same person for whom the unit the joule is named. Use the following experimental data to create a scatter graph of the power (P, on the ordinate) and current (I, on the abscissa).

Current (I) [A]	0.50	1.25	1.50	2.25	3.00	3.20	3.50
Power (P) [W]	1.20	7.50	11.25	25.00	45.00	50.00	65.00

To determine

Create a scatter graph of the Power and Current using the given data.

Explanation of Solution

Description:

Step 1: Open the Excel Sheet, and enter the data as shown in Figure 1.

Figure 1

Step 2: Select all the data from Current and Power column, including the ‘Current’ and ‘Power’ cell.

Step 3: Now, go to the Insert tab in the Excel and click on the Scatter Plot.

Step 4: Label the axis of the plot properly as per the format shown below.

$\text{Label}\text{format:Variable}\left(\text{symbol}\right)\left[\text{unit}\right]$

Step 5: Mention the title of the plot as shown in Figure 2.

Conclusion:

Hence, the scatter graph of the Power and Current is created.
