Chapter 11.2
Electric Power and Compound Circuits
Add a second bulb in parallel and the first one does not dim at all; add it in series and both go dim. Which bulb is brightest is a question about power, not current alone.

By the end
- 01Compute the power delivered to a circuit element and rank bulb brightness with it
- 02Reduce series and parallel resistor networks to an equivalent resistance
- 03Model a real battery as an ideal emf with internal resistance and find its terminal voltage
- 04Place ammeters and voltmeters correctly and describe qualitatively how a nonideal meter disturbs a reading
