The equivalent resistance between points $A$ and $B$ in the following electric circuit is:

You are given three equal resistors. The number of resistances which can be obtained by joining them in series and in parallel grouping is

What will be the equivalent resistance between points $A$ and $B$ of the following electric circuit?

Two students perform experiments on series and parallel combinations of two given resistors $R_{1}$ and $R_{2}$ and plot the following $V-I$ and $I-V$ graphs. Which of the graphs is (are) correctly labelled in terms of the words 'series' and 'parallel'? Justify your answer.

Two resistors of $3 \Omega$ and $6 \Omega$ are connected in parallel. The equivalent resistance $R$ is:

Three incandescent bulbs of $100\, W$ each are connected in series in an electric circuit. In another circuit,another set of three bulbs of the same wattage are connected in parallel to the same source. Now,if one bulb in both the circuits gets fused,will the rest of the bulbs continue to glow in each circuit? Give reasons.
