The pointer of a moving coil instrument gives full scale deflection of 20mA. The potential difference across the meter when carrying 20mA is 400mV.The instrument to be used is 200A for full scale deflection. Find the shunt resistance required to achieve this. If the instrument to be used as a voltmeter for full scale reading with 1000V, then find the series resistance to be connected it?
