Tractor Tech Practice Flashcard 1

Ohm’s Law is represented by which of the following: Volts(E) = Amperes(I) x Ohms (R), Amperes = Volts(E) / Ohms(R), Ohms = Volts(E) / Amperes(I), All of the above?

Low voltage electronic connections can oxidize and corrode, causing high-resistance circuit malfunctions that can be improperly diagnosed as open-circuit malfunctions even though they are still physically connected. True or False?

Ohm’s Law is the mathematical relationship between E, I, and R, which states it will take 1 volt to push 1 Amp of current through 1 Ω of resistance.

The electrolyte in a wet-cell battery is a mixture of sulfuric acid and water, and can cause acid burns

A shorted circuit occurs when there is a break in the wire or the wire connection at a load

Gasoline contains on an average more BTU per gallon than diesel fuel.

Two gears are in mesh; Gear A has 12 teeth; Gear B has 24 teeth. When Gear A has made one complete revolution, Gear B has traveled ½ of a revolution

Hydraulic pressure is created by

A large “driving” gear will drive a smaller “driven” gear more slowly but with greater torque.

For efficient combustion, the air-fuel ratio (by weight) for diesel engines can go as high as 40:1
