Q.

Three incandescent bulbs of $100\mathrm{W}$ each are connected in series in an electric circuit. In another circuit, another set of three bulbs of the same wattage is 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.

Q. In a circuit with one bulb, another identical bulb is added in series. Which of the following is observed?

1. They do not glow.
2. The brightness of the individual bulb reduces.
3. The brightness of the individual bulb increases.
4. The bulbs get fused.

Q. Statement I: In a parallel circuit, the electricity has more than one path to flow through.
Statement II: To make a battery of two cells, the negative terminal of one cell is connected to the negative terminal of the other cell.

1. Statement I is incorrect and statement II is correct.
2. Statement I is correct and statement II is incorrect.
   
3. Both statement I and statement II are correct.
   
4. Both statement I and statement II are incorrect.
   

Q. Which of the following statements is/are correct for a series type of connection in an electric circuit?
