i)-Design an Ayrston shunt to provide an ammeter with current ranges of 1.001A, 4.001A and 19.001A, a d Arsonaval movement with an internal resistance R=1000 , protection resistance 19KN and full-scale deflection current of 1 mA. Calculate Ra, Rb, RC, (with drawing). Q2) - A meter movment has an internal resistance of 100 n and requires 1000MA, dc for full-scale deflection shunting resistor plased across the movement, has a value of 200, Diodes D1, D2, have an average forward Resistance of 4000 each and are assumed to have infinite resistanse in the Reverse direction. For (10 V, 100V, 250V, 500V) ac range, Calculate a-the value of multiplier Rs1,Rs2,Rs3, Rs4. b- the voltmeter sensitivity on the ac range. i)-Design an Ayrston shunt to provide an ammeter with current ranges of 1.001A, 4.001A and 19.001A, a d Arsonaval movement with an internal resistance R=1000 , protection resistance 19KN and full-scale deflection current of 1 mA.
