Find the value of shunt resistor Rsh, that should be connected in parallel to meter to measure a 6mA, 70mA, 700mA & 5A current. The full scale current, Im of the meter is 3mA and has a resistance Rm of 4000 2. Draw the ammeter and mark Rsh. (5 Marks) With a neat diagram and torque equation explain the permanent magnet moving coil (PMMC) type instrument in detail. (5Marks)
