Answer 1

Yes, the total current delivered to multiple devices in parallel is the sum of the individual branch currents (the vector sum if there is inductive load).

Circuit breakers are resettable automatic switches that help protect against circuit overload (such as running too many hair driers and heaters on at one time) and faults (such as dropping the hair drier into a bathtub). Circuit breakers "operate" (or open) to stop current flow to the fault or overloaded circuit.
