Depict a figure showing the arrangement of three resistors in a circuit to get an effective resistance of 4 Omega

Find the effective resistance of the circuit given below:

Three resistors R_1, R_2, R_3 are to be combined as shown in the figure. Which combination has lowest resistance. Arrive at the expression for the effective resistance of this combination

A set of 'n' identical resistors each of resistance R ohm. When connected in series have an effective resistance of X ohm and when the resistors are connected in parallel, the effective resistance is Y ohm. Find the relation between R, X and Y.

10 resistors of 2 Omega each are connected in parellel. Calculate the effective resistance.

Resistance are used to reduce the current flow in a circuit. Resistance can be connected in series and parallel to obtain the required value of resistance. Derive an expression for the effective resistance when three resistors are connected in parallel.
