Construct the circuit below.
Enter the values of the DC voltage and Resisters that you used.
Use a voltmeter to measure the potential difference and resistances.
Enter the measured and predicted quantities in the table below
Use Kirchoff's laws to predict the current values and compare them to your measurements by filling in the table below.
|Variable||Measured Value||Predicted Value||% Difference|
Measure the internal resistance of your power source by graphing the potential difference on the x-axis and the current on the y-axis for several values of the resistanceshown in the circuit below. Begin with and then decrease it by a factor of 5 for each subsequent measurement. You can use a volt meter to measure the current and potential difference.
