660 APPLIED SCIENCES 14 Give some account of the following persons Achan Ehud Abimelech the son of Gideon Doeg Abishai Asahel Nathan Ahithophel Amasa Benaiah II -Plat matt See Department of General Literature and Science pages 624-642 III fyviit SECOND AND THIRD YEARS Explain how to measure the force between two small spheres charged with electricity by means of Coulomb's torsion balance If two small spheres are charged with quantities of electricity in the ratio of to how will the repulsion between them be affected if for an instant they be brought into contact with one another Describe the action of the quadrant electrometer and give the method of comparing the electromotive forces of different batteries by means of it Explain the principle of Wheatstone's Bridge and show how to employ it to determine the internal resistance of battery by Mance's method Explain method of finding the position of fault in telegraph line AB The resistance of telegraph line when perfect is 72 ohms when there is partial fault the resistances as measured from when the end Β is insulated uninsulated are 525 ohms and 35 ohms respectively find the position and resistance of the fault What is meant by electromotive force State the laws which determine the strength of current which battery of given electromotive force will produce in circuit of given resistance battery of 12 cells is joined up so as to give the strongest current through resistance of 14 ohms the resistance of each cell of the battery is 12 ohms what is he arrangement of the cells copper wire coiled on the rim of circle has its two ends attached to galvanometer and the coil is capable of rotating about diameter of the circle describe and account
