- We propose a new model for the origin of Fast Radio Bursts (FRBs), attributing these phenomena to sudden discharges of accumulated electric charge in the accretion disk of compact objects such as black holes. Our framework demonstrates how Compton scattering within the disk plasma generates charge separation, creating a capacitor-like system stabilized by the equilibrium between radiation pressure and electrostatic forces. We detail the discharge process through destabilizing mechanisms in this capacitor, resulting in radiative emission. We compare our model's prediction on radiation signatures with observational data, using FRB2018725A as an example to obtain key quantitative relationships. Additionally, we estimate the total charge buildup via Compton scattering for a stellar-mass black hole, constrained by the best-fit between our model and observations, and determine the corresponding electron density in the accretion disk for this mechanism to operate.
