MECP Basic 2025/2026 Exam Questions
and Verified Answers | Already Graded
A+
Alternating Current (AC) - 🧠 ANSWER ✔✔Energy that alternates back and
forth at a certain frequency that is measured in hertz.
(IMPORTANT): Audio signals are also measured in AC.
Accessory Power - 🧠 ANSWER ✔✔The source of power that gives 12 volts
when the ignition key is in the ACC, and RUN positions, BUT NOT at
START.
Alternator - 🧠 ANSWER ✔✔Generates AC voltage, and rectifies it into DC
Voltage, The alternator is the primary source of the vehicles power while
the engine is running.
Anode - 🧠 ANSWER ✔✔The positive pole of a diode
Bandpass Filter - 🧠 ANSWER ✔✔A device which incorporates both high-
pass and low-pass filters in order to limit both ends of the frequency range.

, Bass - 🧠 ANSWER ✔✔Low audio frequency considered to be below 125
Hz.
BCM - 🧠 ANSWER ✔✔Body Control Module
Bluetooth - 🧠 ANSWER ✔✔Short-Range protocol allowing connections to
wireless devices on a 2.4 GHz band up to 30 feet.
Brain - 🧠 ANSWER ✔✔The common term used to refer to the main control
unit of a security system.
Cathode - 🧠 ANSWER ✔✔The negative pole of a diode
Clipping - 🧠 ANSWER ✔✔Distortion that occurs when a power amplifier is
over driven. This can be seen visually on an oscilloscope. the peaks of a
wave form are "clipped off" at the signal's ceiling.
Crossover - 🧠 ANSWER ✔✔A device that separates the different frequency
bands and redirects them to different components.
Current - 🧠 ANSWER ✔✔The rate of electrical flow through a conductor
between objects of opposite charge, symbol is "i" or "A" measured in Amps.
Direct Current (DC) - 🧠 ANSWER ✔✔A flow of electrons that travels only in
one direction.
