Question

fmhe-2 electrical and electronics systems
with a variable reluctance sensor, what type of reading will a broken magnet cause?
select one:
a. high voltage
b. accurate pressure
c. faulty meter
d. low voltage

Explanation:

A variable reluctance sensor relies on a magnet to generate a magnetic field. A broken magnet will reduce the magnetic field strength, which in turn reduces the induced voltage signal. This leads to a low - voltage reading. Option a is incorrect as a broken magnet won't increase voltage. Option b is incorrect because a broken magnet disrupts the sensor's operation, so accurate pressure (related to the sensor's output context) won't be measured. Option c is incorrect as a broken magnet causes a low - voltage reading, not a faulty meter (a faulty meter is a different issue related to the meter itself, not the magnet - induced signal).

Answer:

d. Low voltage
