1.	The following apparatus is available in a laboratory. Cell:Adjustable from 0 to 1.5 volt Resistor:4Omega and 12Omega Ammeters:A_(1) of range 0 to 3 A, Least count 0.1 A A_(2) of range 0 to 1 A , Least count 0.05 A Voltmeters:V_(1) of range 0 to 10 V, Least count 0.5 V V_(2) of range 0 to 5 v, Least count 0.1 V Find the best combination of ammeter and voltmeter for finding the equivalent resistance of the resistors.
Answer» Solution :The overall RANGE of the VOLTAGE is from 0 to 1.5 V and that of CURRENT is from 0 to `(1.5)/(3)A=0.5A` . We, THEREFORE, prefer instrument that cover these ranges and also have a better least count.
