Technician A says that daytime running lights (DRLs) light the headlights, usually at reduced intensity, whenever the engine is running. Technician B says high-intensity discharge (HID) headlights are brighter and have a yellow tint. Who is right?

technician A is right

Explanation:

Daytime running lights are auxiliary lights that allow other cars to see us better. They are not intended to illuminate the road, so their intensity is low.

Consequently technician A is right

HID lights are high intensity lights, generally bluish-white in color, yellow lights are halogen lights with lower intensity than HID lights.

Consequently, technician B is wrong

a, c, d, e are all applying about success strategies.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
