It’s a reasonably ok metaphor for talking about power transfer but not information transfer. Analytical solutions for charge and fluid flow reduce to very similar differential equations. However for information flow, the models don’t actually require charge to be exchanged, only that we can measure the fields which result from moving charge around. This means the boundary conditions for information transfer are established by quantum effects in the receiver. Literally the Brownian motion of doped semiconductor material expressed in terms of thermal entropy. That establishes the floor for how many individual atoms must do something coherently for it to be statistically separable from what atoms do without an information stimulus.
