2. How does the current in each resistor (I₁, I2, I3) compare to one another and to the current in the battery (IB)? 3. How does the electric potential difference across the battery (AVB) compare to the summative electric potential differences of the three resistors (AV₁ + AV₂ + AV3)? 4. 5. Write the above relationship as an equation: Calculate the ratio of electric potential difference to current for the battery. AVB/IB = How does this ratio compare to the resistance values of the resistor? Attempt to write an equation relating the AVB/IB ratio to R₁, R2, and R3 values. 6. Alter the values of the battery voltage and the resistance of the resistors so that each resistor has a different resistance. Then make measurements and complete the table. Current (1) Resistance (R) a. Element B 1 b. 2 3 7. Using values from the circuit analyzed in Question #6, identify as many mathematical equations as you can that relate AV, I and R for individual circuit elements or for the circuit as a whole. For each equation that you write, demonstrate its validity by substituting in values from the table above. Equation Demonstration of Equation's Validity Electric Potential Difference (AV)
