Direct Current (DC) - ANSWER✔✔a steady flowing type of electricity, produced
by batteries and used in flashlights, boom boxes, and computers.
Voltage - ANSWER✔✔Annotated as a capital V, force that affects the rate at
which electricity flows through a conductor (aka: electrical pressure). The higher it
is the more likely electricity will "leak" across an insulator or an air gap.
Resistance - ANSWER✔✔is the opposition of a material to the flow of electricity
through it. ALL circuits must have this. If they do not they are then considered
short circuits which can lead to wires overheating
Amperes - ANSWER✔✔Annotated as a capital A, represents current strength
Ohms - ANSWER✔✔Annotated as Ώ, represents the measurement of the
resistance in any circuit.
Watts - ANSWER✔✔Annotated as a capital W, represents the measurement of
power consumed by an electrical device.
Circuit Rule - ANSWER✔✔Current is the same at all points in a series circuit.
Voltage is the same at all points in a parallel circuit.
Typical Wiring - ANSWER✔✔3 Wires (black, white, bare) Black- hot conductor,
White - grounded conductor aka neutral, Bare - Alternative route utilized in case of
an emergency.
Ohm's Law - ANSWER✔✔Describes the relationship between voltage, amperage,
and ohms:
A = V/ Ώ
The Law of Electrical Power - ANSWER✔✔used to calculate the amount of power
consumed by an electrical or electronic device:
W=VxA
, Finding Resistance in a Circuit - ANSWER✔✔Series - add the resistance of each
load
Parallel - add the inverses of the resistance
Memorize this order of operations in an Otto cycle engine -
ANSWER✔✔INTAKE - The piston moves down, creating a partial vacuum in the
cylinder. The fuel air mixture enters the cylinder through the open intake valve.
The exhaust valve is closed.
COMPRESSION- Both valves are closed. The piston moves up, compressing the
fuel-air mixture to about ten times atmospheric pressure.
POWER- The spark plugs fire, starting an explosion inside the cylinder. The
resulting high pressure pushes the piston down.
EXHAUST- The piston moves up again, with the exhaust valve open and the
intake valve closed. The piston pushes burned exhaust gases into the exhaust
manifold and out of the engine.
Viscosity - ANSWER✔✔measures the thickness of the oil. Measured by S.A.E.
numbers which range from very light SAE 5 to SAE 90, typically for regular
driving oil is rated at SAE 30 to 40.
Automobile Engine Troubleshooting - ANSWER✔✔1 A "ping" or "knocking"
sound on acceleration usually means that you need a higher octane gasoline. The
noise indicates that the fuel-air mixture is igniting too soon inside the cylinder.
2 A squealing noise that increases with engine speed indicates a loose or worn fan
belt.
3 An engine that runs extremely rough may have a failed spark plug or some other
problem within the ignition system.
4 General sluggishness, roughness, or poor fuel mileage all indicate the need for a
tune-up.
5 Loud clanking sounds may indicate major engine problems that will only get
worse if you ignore them.
The differential has three jobs: - ANSWER✔✔1 Allow different movement of the
two axels, so that the car can turn a corner.
2 Change drive directions. In rear-wheel-drive cars, it connects to the drive shaft
that runs from front to back and powers the axles, which run from side to side.
3 Increase Power. It usually reduces the drive speed, so that three to four input
revolutions create one turn of the axles.
