Using the potential differences already measured, calculate the value of the electric potential difference across the 12 Q2 resistor. Now use the voltmeter to measure the electric potential difference across the 12 Q resistor. Does the voltmeter reading verify your calculation? You know that the total resistance in a simple series circuit can be found by simple addition. Calculate this value. Now, using the values for electric current in the circuit and the total electric potential drop across the circuit, calculate the total resistance using Ohm's law. How do these values compare Is the total resistance in a simple series circuit greater than, less than or the same as the resistance of any one individual resistor? How would adding another resistor in series affect the total current, total drop in electric potential, and total resistance of the circuit? Try it and take the measurements necessary to confirm your answer.
