Electrical (A6)第 73 / 120 题
Technician A says a fuse that blows again immediately after replacement indicates a short to ground or an overload. Technician B says repeatedly replacing the fuse will fix the circuit. Who is correct?
a.Technician A only
b.Both A and B
c.Technician B only
d.Neither A nor B
解析
A fuse that blows again immediately is protecting the circuit from a short to ground or an overload drawing excess current. Technician B is wrong because the underlying fault, not the fuse, must be repaired. Inspect the wiring for chafing and test the component.
