MECHANICAL AND ELECTRICAL TEST 4 QUESTIONS AND ANSWERS | MECHANICAL &
ELECTRICAL EXAM PREP 2026/2027
electrical conductivity - ANS ✔✔A flow of electric charge through a conductor
Conductors - ANS ✔✔Carries electrical current without providing to much resistance current
Insulators - ANS ✔✔Materials that resist the flow of electricity
semiconductor - ANS ✔✔Materials that are neither good conductors or insulators
Current flow - ANS ✔✔Caused by electromotive force or voltage
Amperage - ANS ✔✔The rate of the current flow and may be referred to as inductive flow
Resistance - ANS ✔✔The ability of a conductor to resist current flow and is measured in OHMS
Ohms law - ANS ✔✔E=IR
Power - ANS ✔✔The rate at which work is accomplished. Work or energy released divided by
time
Billing for energy consumption is. - ANS ✔✔I'm kilowatt hours kWh
Simple circuit - ANS ✔✔Composed of a power source
, Simple circuit load - ANS ✔✔And electrical component or group of components that consume
electricity
Simple circuit conductor - ANS ✔✔A set of conductors that carry current from the source to the
load
Closes circuit - ANS ✔✔An uninterrupted path that allows a continuous flow of current through
and electrical current.
Open circuit - ANS ✔✔When the path of current flow is interrupted Such as if a circuit is open,
(turned off)
Short circuit - ANS ✔✔When an inadvertent shortcut develops in a circuit that permits current
flow through an unintentional path.
series circuit - ANS ✔✔Connected so that current passes through each open component in the
circuit without branching off to individual components in the circuit
Parallel circuit - ANS ✔✔Current branches off to individual components in the circuit
Direct current - ANS ✔✔Current flow in on direction
Alternative current - ANS ✔✔Continuous reversal of the direction of current flow such that a
point in time the current flow is in one direction and at another point in time it is in the reverse
direction
Single phase alternative current - ANS ✔✔Distribution system refers to a system in which all of
the voltage of supply vary in unison
