The following should be visible/indicated in this photo: Your name and the date The three connected lamp receptacles, with the lamp in position R 1 unscrewed and battery holder while circuit is on. Insert photo here Photo 12 10 © 2016 Carolina Biological Supply Company
The following should be visible/indicated in this photo: Your name and the date The three connected lamp receptacles, with the lamp in position R 2 unscrewed and battery holder while circuit is on. Insert photo here Observation: Lights go out when you unscrew the bulb 1. Based on the brightness of the lamps when they are all connected, which current is the greatest? Which current is the smallest? Why? Greatest R1 smallest r3 because it distributes the voltage equally 11 © 2016 Carolina Biological Supply Company

2. What happens to the lamps when resistor R 1 is disconnected? Lights go out 3. What happens to the lamps when resistor R 2 or R 3 is disconnected? R1 gets brighter 4. What happens to the lamps when resistor R 4 is disconnected? Nothing 5. Which exhibits the larger voltage drop, R 1 or R 4 ? It would stay the same. 6. What would happen to the brightness of the lamps if all the resistors were connected in series? In a series circuit, as more bulbs are added, the brightness of each bulb decreases. This is because the resistance R increases which causes the current to pass through each bulb to decrease. 12 © 2016 Carolina Biological Supply Company
