1. Visualization of internal resistance created by a battery
|Step(s) to Follow||Expected Result|
1. Set power supply to 9V.
2. Connect the 2 lamps to the power supply.
3. Add the 3rd bulb.
|Bulbs do not dim - current increases to ~5 A|
1. Connect the 2 lamps to the 9v battery.
2. Measure and note the voltage drop across 1 bulb.
3. Add 3rd bulb in parallel.
4. Measure and note the voltage drop across 1 bulb.
|Bulbs will dim as the 3rd bulb is added; voltage drop will increase|
