Analyzing Circuits { Ass. Statements 5.2.1 – 5.2.8 due Wed., Dec. 11 Quiz on Topic 5 (electric circuit analysis) on Wed., Dec. 11 On your whiteboards, sketch each of the following: A. A circuit with 3 resistors in series with a 12 V cell. B. A circuit with 3 resistors in parallel with a 6.0 V cell. C. A circuit with a single resistor in series with 2 resistors that are in parallel with a 9.0 V cell. Review The total potential supplied by the source must be “used up” by the components of the circuit. The sum of the potential drops across each component in a series circuit will be equal to the total potential supplied by the source The electrons going through parallel branches will each experience the same drop in potential by the time they meet up again in the main circuit Kirchoff’s Voltage Rule The total current passing through a circuit depends on the total resistance. Current leaving the potential source is the same as the current entering the potential source (it’s not “used up”) Current must pass equally through all components in series with each other When current reaches a junction, it will split. The sum of the currents entering a junction will be equal to the sum of the currents exiting a junction Kirchoff’s Current Rule
