If 3 resistances of 3 ohm each are connected in parallel, what will be their total resistance?

If five resistances, each of value 0.2 ohm, are connected in series, what will be the resultant resistance?

State the law of combination of resistances in parallel.

How should the two resistances of 2 ohms each be connected so as to produce an equivalent resistance of 1 ohm?

Two resistances X and Y are connected turn by turn : (i) in parallel, and (ii) in series. In which case the resultant resistance will be less than either of the individual resistance?
