Some voltage must be present but the current causes the arcing.
A shorted coil or shorted coils in the rotor will cause arcing at the commutator. It should also be noted that if the brushes are damaged badly enough where they make contact with the commutator, this can cause arcing. Oh, and let's not forget that a stuck brush or brush spring will prevent a brush from making proper contact with the commutator. Arcing can result from that, too.
Arcing is electrical current jumping across a gap, or creating an arc, as in a spark plug firing, or lightning arcing across the sky.

high voltage breaking capacity
You have a wire that is loose and arcing.
Arcing is caused by a poor electrical connection. The breaker is not making good contact with the buss bar. Try replacing the breaker.
Always push start your car.
An arcover is the unwanted arcing of electricity from one component to another.
It's common to put arcing horns on the HV side of a power transformer to short out voltage spikes arriving from lightning strikes along the line.
If I understand your question correctly, arcing is when an electrical charge jumps inside the distributor from the main electrical prong to the prongs that supply electric power to the spark plugs.Hope this helped,Evan
The anagrams are arcing, caring and racing.
