In an experiment to study the relationship between the potential difference across a resistor and the current through it, a student recorded the following observations:
Find in which one of the above sets of readings the trend is different from others and must be rejected. Calculate the mean value of resistance of the resistor based on the remaining sets of readings.
Three bulbs each having power P are connected in series in an electric circuit. In another circuit another set of three bulbs of same power are connected in parallel to the same source.
i. Will the bulbs in both the circuits glow with the same brightness? Justify your answer.
ii. Now let one bulb in each circuit get fused. Will the rest of the bulbs continue to glow in each circuit? Give reason.
