1) Had you made the end corrections of the meter bridge before you performed the experiment? How should the equation (1) be modified to make end corrections? [0.5] Ans: 2) On what factors does the specific resistance depend? [0.5] Ans: 3) Why is it advantageous to use the key K? Why should it be kept open while taking the measurements and performing other calculations, after you detect the null point? [0.5] Ans: 4) The meter bridge's wire should be made of a material of low thermal coefficient of resistivity. It means that the specific resistance of the wire's material should not vary much with temperature. Explain why. [0.5]
