Question

what is the value of the shunt resistance
that allows Go % of the
main current
through
the
glavanometer of lood?​

Answer 1

Answer:

Shunt resistors have a maximum current rating. The resistance value is given by the voltage drop at the maximum current rating. For example, a shunt resistor rated with 100A and 50mV has a resistance of 50 / 100 = 0.5 mOhm. The voltage drop at maximum current is typically rated 50, 75 or 100 mV.
