A PMMC instrunment with Rm=1.3Kohm and FSD =500micro ohm  is used in a multirange  DC Voltmeter. The Series-connected multiplier resistors are R1=38.7Kohm ,R2=40Kohm  and R3=40Kohm .Calculate the three voltage ranges and determine the Voltmeter sensitivity?

A 12V source supplies 25 A to load .Calculate the load current that would be measured when using an ammeter with a resistance of (a)0.12 ohm (b)0.52ohm and (c)0.002ohm?
