V = I x R where
V represents voltage, I represents current, and R represents resistance
correlates to this law.
Ohm's law
Refer to figure 28:
The bottom view of the object show is which picture?
Picture 2
This is the method used to rapidly charge a nickel-cadmium battery.
Constant voltage and varying current
This type of measurement is used to designate the arm in weight and balance computations.
Distance
The lever arm is the distance from the fulcrum to the item in question, and is measured in inches.
Many areas of aviation have shifted their focus from eliminating error to what?
Preventing and managing error
This happens to the current in a voltage step up transformer with a ratio of 1 to 4.
The current is stepped down by a ratio of 1 to 4.
A specific measured distance from the datum or some other point identified by the manufacturer, to a point in or on the aircraft is called this type of number.
Station number
The electrolyte of a nickel-cadmium battery is lowest when the battery is in what condition?
Discharged condition
In decimal format, what is the following equation equal to?
3.47 x (10^(-4))
.000347
An Airworthiness Directive required that a propeller be altered. Certificate mechanics could perform and approve the work for return to service it if is what type of repair or alteration?
Minor repair or alteration
Total resistance will be smaller than the smallest resistor in this type of circuit?
Parallel circuit
This is the name of the drawing line that consists of alternating long and short lines.
Center line
One can expect this result if water is added to a nickel cadmium-battery when it is not fully charged.
Excessive spewing is likely to occur during the charging cycle.
Refer to figure 61: How many pounds of force is applied to rope A to lift the weight?
15 pounds
60 lbs / 4 rope strains = 15 lbs
These are the three types of human error.
Omission, commission, and extraneous
True power is what in comparison to the apparent power in a reactive or inductive ac circuit.
True power is less than the apparent power.
An orthographic projection contains how many possible views?
Six
Although, one view, two view, and three view drawings are most common.
In reference to a nickel-cadmium battery, improperly torqued cell link connections will result in what on the hardware?
Heat or burn marks due to arcing and overheating
Solve the equation to the nearest who number.
(32 x (3/8)) / (1/6)

This part of the Federal Aviation Regulations (FARs) prescribes the requirements for issuing mechanic certificates and associated ratings and the general operating rules for the holders of these certificates and ratings.
14 CFR Part 65
Refer to figure 12:
Find the total resistance in the circuit.
21.2 ohms
Working drawings may be divided into these three classes
Detail drawings, assembly drawings, and installation drawings
A fully charged lead-acid battery will not freeze until extremely low temperatures are reached because most of the acid is in this.
The solution
What is the amount of current that a 30 volt, 1/2 horsepower motor that is 85 percent efficient draw from the bus? (Note: 1 horsepower = 746 watts)
14.6 amperes
(One horsepower is 746 watts and the motor produces one-half horse power so, 373 watts / 0.85 = 438.8 watts of power drawn by the motor.) (I = P / E so 438.8 / 30 = 14.62 amps)
