SUMMARY
Charged black holes, also known as Reissner-Nordström black holes, exhibit characteristics such as charge and spin that are determined at the moment of their formation. Once formed, the event horizon prevents any observable causal effects from within the black hole, meaning external observers can only infer charge based on phenomena that occurred outside the event horizon. The electromagnetic force, mediated by photons, cannot escape a black hole, complicating the detection of its charge. Therefore, any changes in charge after formation are linked to external accretion processes.
