Resistances of two coils of wire are 3 Omega and 6 Omega . If these coils be connected is (i) series and in (ii) parallel combination, then what will be the equivalent resistance in each case ?

Three 4 Omega resistances can be connected in different combinations, The probable values of the equivalent resistance are

A parallel combination of three resistances of 6 Omega, 12 Omega and 12 Omega is connected in series with an electric cell of emf 1.5 V and internal resistance 2 Omega . Find out the currents through the three resistances.

A null point is obtained when two resistors , of resistance r each, are connected in series and placed in the fourth arm of a wheatstone bridge . Now , the resistance R of the third arm is kept fixed ,and r, connected in parallel, are placed in the fourth arm. then a null point is obtained only by interchanging the resistances P and Q , and also the value of r.
