. The value of multiplier resistance required
to enable the instrument to read up to 12V will beA moving coil instrument has an f.s.d. of 10mA
and a resistance of 20. The value of multiplier resistance required
to enable the instrument to read up to 12V will be
The answer is :- 3
For fsd a current of 10mA will flow. Thus total
resistance of the circuit = 12V / 10mA = 12/0.01 = 1200. If the meter's resistance is 20, then the resistance of the shunt must be
1200 - 20 = 1180
