A PMMC meter the has internal resistance of 1000 requires and 1mA fsd current is used to carry voltage measurement in an ac supplied circuit. A shunt resistor with value of 1000 is placed across the meter. The used rectifier is a Half-wave rectifier. The diodes used have a forward resistance of 2000. The voltmeter is need to measure a voltage ranged from 0 to 20V ac. 1- Calculate the value of Rs. 2- Determine the voltmeter sensitivity. 3- Determine the error due to the difference between the RMS and average value of the voltage as a percentage at the maximum range.
