Q21 A PMMC instrument gives 25 mA at full scale reading when a potential difference across its terminals is 32mV. Show that how it can be used (a) as an ammeter for the current measurement in the range of 0 –3 A (b) as a 0 – 510V range voltmeter for the voltage measurement. (c) find the multiplying factor of shunt and AND voltage amplification
