5. a. The circuit below shows four identical bulbs connected to an ideal (resistance-less) battery. Rank the bulbs in order from brightest to dimmest. Use "=" to indicate the same brightness. Explain how the ranking was determined. b. Write an equation that relates the voltage across bulbs 3, 5 and 6 to the battery voltage. c. Bulb 1 is removed from its socket. Does the brightness of bulb 3 increase, decrease or remain the same? Explain your reasoning.
Circuit 3: Three bulbs in series Bulb 1: Voltage across V1 Bulb 2: Voltage across V2 Bulb 3: Voltage across V3 Battery: VBat Current through circuit: I Calculate Power: P1 P2 P3 Show that V = V1 + V2 + V3 b.) Is the current almost the same in all the wires? Calculate the resistance of Bulb 1 (R1), resistance of Bulb 2 (R2), resistance of Bulb 3 (R3); and the total resistance connected to the battery.
