1. The circuit diagram below shows four identical bulbs. Assume all circuit elements and wires are ideal.

a). Given the circuit configuration above, rank the brightness of the bulbs, from brightest to dimmest. You do not need to explain your answer.

b). Bulb D is removed from the circuit. What happens to the brightness of bulbs A, B, and C, compared to how bright they were in the original circuit, as a result? Briefly explain your reasoning.

c). Bulb D is put back into the circuit, but now Bulb A is removed. What happens to the brightness of the bulbs B, C, and D, compared to how bright they were in the original circuit, as a result? Briefly explain your reasoning.

1. The circuit diagram below shows four identical bulbs. Assume all circuit elements and wires are(ideal.) P- B (a) Given the circuit configuration above, rank the brightness of the bulbs, from bright- est to dimmest. You do not need to explain your answer. A > B Z C = D (b) Bulb D is removed from the circuit. What happens to the brightness of bulbs A, B, and C, compared to how bright they were in the original circuit, as a result? Briefly explain your reasoning. P = Zz. R. Bulb B. ( 8 Dance in parallel ( 8 Done in Soing so then ouch! have some comments Bulb A doesn't change because they have sarre current Blightness of \\ is sane because in somes with Dy hat same curent. Ball will get dimmer hemake it is In parallel with Off. so removing 1!! dotoure the current combination. "c) Bulb D is put back into the circuit, but now Bulb A is removed. What happens to the brightness of bulbs B, C, and D, compared to how bright they were in the original circuit, as a result? Briefly explain your reasoning. All of the tomaing bulbs wi'll get bilenter. bepay A will not afford them since they have same met
