Potentiometer and Circuits with symmetry

If voltage is applied between terminals 1 and 2 when terminals 3 and 4 are open the power liberated is P_(1)=40W and when terminals 3 and 4 are connected, the power liberated is P_(2)=80W . If the same source is connected to the terminals 3 and 4, the power liberated in the circuit when terminals 1 and 2 are open in P_(3)=20W . Determine the power P_(4) consumed in the circuit when the terminals 1 and 2 are connected and the same voltage is applied between the terminals 3 and 4.

In Fig. 7.48 , each of the segments ( e.g., AE , GM, etc.) has resistance r . A battery of emf V is connected between A and C . Internal resistance of the battery is negligible. If a potentiometer circuit having gradient k is connected across the points H and C , the balancing length shown by the potentiometer is

When a resistor of 5 Omega is connected across a cell, its terminal potential differnce is balanced by 140 cm of potentiometer wire and when a resistance of 8 Omega is connected across the cell, the terminal potential difference is balanced by 160 cm of the potentiometer wire. Find the internal resistance of the cell.

The following 'precautions' were listed by a student in the experiment on study of 'Dependence of current on potential difference'. (A) Use copper wires as thin as possible for making connections. (B) All the connections should be kept tight. (C) The positive and negative terminals of the voltmeter and the ammeter should be correctly connected. (D) The 'zero error' in the ammeter and the voltmeter should be noted and taken into consideration while recording the measurements. (E) The 'key' in the circuit, once plugged in, should not be taken out till all the observations have been completed. The 'precautions' that need to be corrected and revised are :
