If the resistor in an RC integrator circuit has opened (become disconnected or failed in a way that it no longer conducts electricity), the circuit would fail to charge the capacitor, leading to the system not turning on at all. This is because the resistor is crucial for limiting the current that charges the capacitor, and without it, the charging path is broken.
