You are given three resistors of 1 ohm each. Show that they can be grouped in four different ways and calculate the combined resistance in each case.

(a) what is meant by series and parallel combination of resistances ? (b) in which case, series combination or parallel combination, the combined resistance is less than any of the individual resistances ? (c ) How should two resistance of 2 Omega each be connected so as to produce an equivalent resistance of 1 Omega ? In the circuit diagram given here , find: (i) total resistance of the circuit (ii) total current flowing in the circuit, and (iii) the potential difference across R_(1)

(a) Three resistors 1 Omega, 2Omega and 3 Omega are combined in series. What is the total resistance of the combination ? (b) If the combination is connected to a battery of emf 12 V and negligible internal resistance, obtain the potential drop across each resistor.
