Parallel Combination

A uniform wire of resistance R and length L is cut into four equal parts , each of lengths L/4, which are then connected in parallel combination. The effective resistance of the combination. The effective resistance of the combination will be

Draw the circuit diagram of an electric circuit containing a battery of 6 V, a key , an ammeter , a resistor of 4 Omega in series with a combination of two resistors of 8 Omega each in parallel, and a voltmeter across the parallel combination. (a) Calculate the resistance of the circuit . (b) Find the current flowing in the circuit. (c) What will be the voltage across the parallel combination of resistors?

Explain with diagrams what is meant by the "series combination" and "parallel combination" of resistances. In which case the resultant resistance is: (i) less, and (ii) more, than either of the individual resistances?
