A shunt generator can self-excite only if the resistance of the field circuit is less than the critical value. This is because the field circuit needs to allow enough current to flow to generate the initial magnetic field necessary for the generator to start producing electricity. If the resistance is too high, it will limit the current too much, preventing the generator from self-exciting.
