Three incandescent bulbs of 100 W each are connected in series in an electrical circuit. In another circuit another set of three bulbs of the same wattage 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. 2. Compare the power used in 2 ohm resistor in each of the following circuits a)6 volt battery in series with 1 ohm and 2 ohm resistors b)4 volt battery in parallel with 12 ohm and 2 ohm resistors
