Electrical (A6)第 64 / 120 题
Technician A says a voltage-drop test across a battery cable can reveal unwanted resistance. Technician B says a voltage-drop test is more accurate than a visual inspection for finding poor connections. Who is correct?
a.Technician A only
b.Technician B only
c.Both A and B
d.Neither A nor B
解析
A voltage-drop test measures the voltage lost across a connection under load, so high drop reveals corrosion or loose connections that a visual check may miss. Both technicians are correct. Acceptable drop is typically a few tenths of a volt or less.
