Not enough current to supply load

Question

Are there cases where a power supply can offer xV, which is required by a device, but be unable to supply enough current?

For example, a voltage divider not only lowers voltage, but limits the current. Wouldn't this be an issue for several components?

Farcher · Answer

Power supplies are all limited by the power (voltage $times$ current) they can supply either because there is some mechanism within the supply to limit the power (or current) which could even be a fuse or because the power supply has an internal resistance.
