The sharing of current between different components in an AC circuit
This type of circuit is known as a parallel circuit.
In a parallel circuit there are multiple possible pathways for the current to flow.
I think that the questioner is asking what is the difference between an isolator and a circuit breaker.A circuit breaker is a switching device designed to interrupt a fault current.An isolator is not intended to break a live circuit but, rather, to provide a visible separation between a circuit component and live conductors.For example, isolators (or 'disconnectors' in US parlance) are located on either side of a high-voltage circuit breaker. If the circuit breaker requires maintenance, then the procedure is to:a. trip the circuit breaker.b. open the isolators on each side of the circuit breaker, so there is a visible gap between the circuit breaker and the 'hot' conductors.c. apply temporary earths (grounds) between each isolator and the circuit breaker.d. complete a 'permit to work' card.e. begin work.
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
A parallel circuit has the same voltage but different current in each leg and series circuit has the same current but different voltage on each components unless the same value.

That really depends on how the circuit is designed.
Magnetizing inrush current has bigger 2nd harmonics compare to short circuit current. the second harmonics content is about >60% of fundamental harmonic. magnetizing inrush current happened when we energised the transformer, and short circuit current happened if there is a short circuit between different alive phase.
Yes, the neutral wire carries current in an electrical circuit, but it is designed to carry the current back to the power source to complete the circuit.
They divide the electrons between different branches of the circuit.
