A moving-coil instrument has an internal resistance of 175? and gives a fullscale deflection when 12,5 mA flows through it: Calculate: 6.1.1 The value of the shunt resistor needed to convert the instrument to an ammeter that has a range of 0A to 7A. 6.1.2 The value of the multiplier resistor needed to convert the instrument to a voltmeter with a range of 0V to 45V.
