MECP Basic 2025/2026 Exam Questions
with 100% Correct Answers | Latest
Update
What is ohms law? - 🧠 ANSWER ✔✔Uses a mathematical formula to
descibe a specific and measurable relationship between voltage, current,
and resistance
What is an arming delay? - 🧠 ANSWER ✔✔A term used to describe the
elapsed time between the moment a security system is first told to arm and
the moment it is actually armed. This normally only applies to systems that
are passively armed, but can apply to actively armed systems as well
What is resistance? - 🧠 ANSWER ✔✔The opposition to current flow
What is an ohm? - 🧠 ANSWER ✔✔The unit of measurement for electrical
resistance named after Georg Simon Ohm
In Ohm's Law, what is current symbolized as? - 🧠 ANSWER ✔✔"A" for
ampere or "I" for "intensity" of the electron flow
What is required for current flow? - 🧠 ANSWER ✔✔Voltage

, What is rectification? - 🧠 ANSWER ✔✔The process of turning AC into
(pulsing) DC
What is an alternator? - 🧠 ANSWER ✔✔A mechanically driven automotive
device that generates AC electricity & is rectified into DC to power the
electrical accessories in the vehicle. The alternator is the primary source of
vehicle power while the engine is running.
What is frequency measured in? - 🧠 ANSWER ✔✔Cycles per second, or
Hertz (Hz)
What is "DC"/Direct Current? - 🧠 ANSWER ✔✔Current that supplies power
to electronic components, & is either positive or negative in polarity, but not
both
What is "AC"/Alternating Current? - 🧠 ANSWER ✔✔Current that alternates
polarity (or it's magnetic field) between positive and negative
What is the difference between AC & DC electrical current? - 🧠 ANSWER
✔✔AC periodically reverses direction of electrons flowing (back and forth),
while DC always flows in only one direction
