Sample Practice Test Questions

Electronics Information

Voltage and current are __________ proportional.

directly

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.

Automotive Information

The spark plugs fire a few extra degrees before top dead center when the engine is running faster. In this case the engine's timing is:

advanced

Ignition timing defines the point in time at the end of the compression stroke that the spark plug fires. Measured in number of degrees before top dead center (BTDC), the exact point that the spark plugs initiate combustion varies depending on the speed of the engine. The timing is advanced (the spark plugs fire a few more degrees BTDC) when the engine is running faster and retarded when it's running slower.

Automotive Information

The primary purpose of the muffler is to:

quiet exhaust

The muffler follows the catalytic converter and absorbs sound to help quiet load exhaust. It is followed by the exhaust pipe which is the final exit point for exhaust gas from the vehicle.

Shop Information

When using a hacksaw, blades with __________ teeth are more appropriate for cutting thinner materials.

more

A hacksaw has replaceable blades and is used to cut metal. The blade type is chosen based on the material that is to be cut. Blades with larger numbers of teeth per inch are more appropriate for cutting thinner materials.

Word Knowledge
Refurbish most nearly means:
renovate
To brighten or freshen.
Electronics Information

Why does current in an electric circuit create heat?

heat is created when the current overcomes resistance in the wire

Current in an electric circuit creates heat when the current overcomes resistance in the wire.

Automotive Information

Which of the following is not a primary function of a vehicle's lubrication system?

increases fuel economy

The lubrication system lubricates engine components by putting an oil film between them to reduce friction and smooth engine operation, cools by absorbing heat from engine parts, seals the pistons and cylinders to contain combustion, cleans contaminants, and quiets engine noise.

General Science

Water freezing or boiling is an example of which of the following?

phase transition

A substance undergoes a phase transition when it moves from one state of matter to another, for example, when water freezes or boils.

General Science

Which of the following does not filter air as part of the respiratory system?

epiglottis

After air enters through the nose, it passes through the nasal cavity which filters, moistens, and warms it. Further filtering takes place in the pharynx, which also helps protect against infection, and then in the trachea which is just past the epiglottis which prevents food from entering the airway.

Automotive Information

The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber. This describes which engine stroke?

intake

The four-stroke piston cycle of internal combustion engines starts with the piston at top of the cylinder head (top dead center or TDC) during the intake stroke. The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber through the now open intake valve.
