  Three incandescent bulbs of 100 W - 220 V each are connected in series in an electrical circuit. In another circuit another set of three bulbs of the same voltage are connected in parallel to the same source. (a) Will the bulb in the two circuits glow with the same brightness? Justify your answer. (b) Now let one bulb in both the circuits get fused. Will the rest of the bulbs continue to glow in each circuit? Give reason.
