4. i. Briefly explain with the help of a block diagram, the various parts of an electronic multimeter. (5 Marks) ii. In a circuit, a simple shunted ammeter using a basic meter movement, with an internal resistance of 1800 22 and 100 pA full-scale deflection current, indicates 3.5 mA on its 5 mA scale. Using a recently calibrated digital ammeter, 4.1 mA is measured as the reading. This indicates there is a faulty shunt on the 5 mA range of the ammeter. Calculate (a) The actual value of a faulty shunt (b) The current shunt for the 5 mA range. (10 Marks)
