Change In Resistance

Five identical resistors each of resistance 1Omega are initially arranged as shown in the figure by clear lines. If two resistances are added as shown by the dashed lines then change in resistance in final and initial arrangement is

How does the concept of change of resistance of a wire when strained (stretched) has been utilized in technology?

In a series LCR resonance circuit, if we change the resistance only, from a lower to higher value :

Wheatstone Bridge||Stretching of Wire||Reshaping and Resistance Change

Metal wire is connected in the left gap, semi conductor is connected in the right gap of meter bridge and balancing point is found. Both are heated so that change of resistances in them are same. Then the balancing point

A wire of mass m length I, density d, and area of cross section A is stretched in such a way that is length increases by 10% of its original value, Expresss the changed resistance in percentage.

A wire of resistance 1 Omega is stretched so as to change its diameter by 0.25 %. The percentage change in its resistance is

The wire is stretched to increase the length by 1%. Find the percentage change in the resistance.

A wire is stretched 30%, what is the % change in its resistance?

A resistance box, a battery and a galvanometer of resistance G ohm are connected in series. the galvanometer is shunted by resistance of S ohm, find the change in resistance in the be required to maintain the current from the battery unchanged.
