A galvanometer with a coil of resistance 12 ohm shows a full scale deflection for a current of 2.5 mA. calculate the value of the resistance required to convert into
(a)an ammeter of range 0 to 7.5 A
(b)a voltmeter of range 0 to 10 V
(c)draw the diagrams to show how you will connect this resistance to the galvanometer in each case.
