1. Series Circuits Series Circuit – a circuit that contains only one current path Circuit Diagram Constructed Circuit EGR 1011

2. Total Series Resistance EGR 1012 From our Breadboarding Experiment, we found that the total resistance of this circuit is 11.3 kΩ, which happens to be equal to the sum of all of the resistances in the series loop. R T = the total circuit resistance R n = the highest-numbered resistor in the circuit

3. Current in a Series Circuit EGR 1013 Current Characteristics – the current at any point in a series circuit must equal the current at every other point in the circuit

4. Voltage Characteristics of a Series Circuit EGR 1014 The voltages across the resistors “around the loop” add up to the applied Power Supply voltage.

5. What About the Powers? EGR 1015 Sum of the individual resistor powers Power delivered by the source
