17,201 Circuit A: Using the battery at the 9V setting, connect a single light bulb across the battery. Light bulb Circuit B: Add a 100-ohm resistor to circuit A such that the brightness of the light bulb decreases. w R= 100 Light bulb Circuit C: Add a 100-ohm resistor to circuit A such that the brightness of the light bulb stays the same. R= 100 2 Light bulb Circuit D: Add a second light bulb to circuit A such that it shines visibly, but less brightly than the first light bulb. You can add as many resistors as you want. Light bulb A Light bulb B Note: the table has rows for more branches than there are in the circuits. Just fill in as many as there truly are. circuit A #junctions: # branches: list of elements: total resistance: branch 1 branch 2 branch 3 branch 4 branch 5
