The source neutral wire is spliced to the neutral on the receptacle half of the combo device and to the white cable wire running to the light. Wiring a gfci outlet with a light switch in the first diagram the single way switch and light bulb is connected to the load terminal of gfci.
In the second diagram the light switch is connected to the line terminals of gfci. All wires are spliced with a pigtail at the devices to pass current to the next. Wiring multiple outlets and a gfci here a gfci receptacle is added at the end of a row of duplex receptacles for single location protection. With this kind of an illustrative guide you will have the ability to troubleshoot stop and full your projects without difficulty. My short answer to the question is that yes lights and power outlets aka ac receptacles can be on the same circuit controlled by a circuit breaker especially in a single family residential house.
