Period 7 Physics Mr. Waldrep 19 April 2010 Resistors in Series and Parallel Analysis Questions 2. The three resistors added together equal the value of R eq. My lab group calculated R eq to be 29,690 Ohms. The total resistance of the three resistors in series is also 29,690 Ohms so when you compare the two resistances, they are equal. 3. R eq is 29,690 Ohms and the total resistance of the three resistors in parallel is 4,950 Ohms. When you compare these two values, it is clear that there is much less resistance when the resistors are in parallel.

Unformatted text preview: 4a. In circuit one, our R 1 was calculated at 13.31 Ohms. If we went back and replaced our R 1 value with our R eq value, 29,690 Ohms, the power dissipated would be 5.71mW. You would get a much smaller number if you were to change these two numbers because you would originally be dividing by 9,820 Ohms, but now you are dividing by 29,690 Ohms. The total power dissipated in circuit one would become significantly smaller and would become reasonably close to the total power dissipated in circuit #3....
