Can be.
Wire wound resistors might take more power, or offer better precision, or custom resistance values. Wherever, whenever those features are desirable, whether its a series or parallell circuit, a wire wound resistor might be used.
Which type of resistor is commonly used in automotive circuits?
There is no true advantage of RC circuits over RL circuits, as they perform different functions. RC circuits contain resistors and capacitors, while RL circuits contain resistors and inductors.
Switches used in electrical circuits are wired in series with either a parallel or series load. In parallel loads, the switch is upstream from the parallel circuit, so that the switch will shut off all of the parallel circuits.
In a parallel circuit the failure of one bulb reduces the light of that one bulb. In a series circuit the failure of any bulb causes all bulbs to stop producing light because the circuit itself fails. A break in a series circuit stops the current flow to the whole circuit. A break in a parallel circuit stops the flow only in that parallel branch, not the whole circuit. This independence from system loss by one failure is a parallel advantage.
