Plot V p vs V s 1 graph and V p vs V s 2 graph with the data of Table 1 and Table 2 respectively (two differents graphs). You can use Excel, Matlab, wolframalpha.com or any other program to plot. 2. Linear Fit your points. 3. Find their slopes. 4. Calculate the experimental values for N p N s 1 and N p N s 2 with the help of the slopes. 5. Calculate percentage error with the help of the theoretical values. For the second part: 1. Calculate I p and I s 1 with the help of Ohm’s law and fill in Table 3 2. Plot I p vs I s 1 with the data of Table 3 3. Linear Fit your points. 4. Find their slopes. 5. Calculate the experimental value of N p N s 1 using the slope. 6. Calculate the percentage error with the help of the theoretical value. Remember that the percentage error of a value A is: % Error = | A experimental − A measured | A measured 100 3
