Question
Assume that resistances in the circuit represent bulbs. Would the remaining bulbs burn brighter (draw more current), dimmer (draw less current), burn with the same brightness, or extinguish under the following scenarios? Justify your answer:
1) R1 R2 and R3 are connected in series. R2 burns out in circuit.
2) R1 R2 and R3 are connected in parallel. R1 burns out in circuit.
3) R1 R2 and R3 are connected in parallel. R1 and R3 burn out in circuit.
4) R2 and R3 are connected in parallel. R1 is connected in series with R23. R3 burns out in circuit.
Explanation / Answer
(1) R2 burns out in circuit dimmer.
(2) R1 burns out in circuit brighter.
(3) R1 and R3 burn out in circuit with same brightness.
(4) R3 burns out in circuit dimmer.
