equal to the inductance of the highest rated inductor. equal to the sum of the individual inductances. less than the inductance of the lowest rated inductor.
If both the volume and the absolute temperature of a confined gas are doubled, the pressure will: not change be halved become four times as great.
If a double-actuating cylinder in a 3,000 PSI system has a piston with a surface area of three square inches on the extension side, and a rod with a cross-section area of one square inch attached to the piston on the other side, approximately how much force will the actuator be able to produce when retracting? 9,000 pounds 6,000 pounds 3,000 pounds.
A wing with a very high aspect ratio (in comparison with a low aspect ratio wing) will have: increased drag at high angles of attack a low stall speed poor control qualities at low airspeed.
An increase in the speed at which an airfoil passes through the air increases lift because: the increased speed of the airflow creates a greater pressure differential between the upper and lower surfaces the increased speed of the airflow creates a lesser pressure differential between the upper and lower surfaces the increased velocity of the relative wind increases the angle of attack.
The purpose of stall strips on airplane wings is to: increase lift in areas of installation prevent stall in the areas of installation ensure that the wing root areas stall first.
What is the purpose of the ground symbol used in electrical circuit diagrams? to show that there is common bus for connection of the source of electrical energy to the load to show the source of electrical energy for the load to show that there is a return path for the current between the source of electrical energy and the load.
What is the operating resistance of a 30-watt light bulb designed for a 28-volt system? 1.07 ohms 26 ohms 0.93 ohms.
Which statement is correct when made in reference to a parallel circuit? the current is equal in all portions of the circuit the total current is equal to the sum of the currents through the individual branches of the circuit the current in amperes can be found by dividing the EMF in volts by the sum of the resistors in ohms.
If three resistors of 3 ohms, 5 ohms, and 22 ohms are connected in series in a 28-volt circuit, how much current flow through the 3-ohm resistor? 9.3 amperes 1.05 amperes 0.93 amperes.
A circuit has an applied voltage of 30 volts and a load consisting of a 10-ohm resistor in series with a 20-ohm resistor. What is the voltage drop across the 10-ohm resistor? 10 volts 20 volts 30 volts.
The end-of-charge voltage of a 19-cell nickel-cadmium battery, measured while still on charge, must be 1.2 to 1.3 volts per cell must be 1.4 volts per cell depends upon its temperature and the method used for charging.
Nickel-cadmium batteries which are stored for a long period of time will show a low liquid level because: of the decrease in the specific gravity of the electrolyte electrolyte evaporates through the vents electrolyte becomes absorbed into the plates.
How can the state-of-charge of a nickel-cadmium battery be determined? by measuring the specific gravity of the electrolyte by a measured discharge by the level of the electrolyte.
What may result if water is added to a nickel-cadmium battery when battery is not fully charged? excessive electrolyte dilution excessive spewing is likely to occur during the charging cycle no adverse effects since water may be added anytime.
The working voltage of a capacitor in an AC circuit should be: equal to the highest applied voltage at least 20 percent greater than the highest applied voltage at least 50 percent greater than the highest applied voltage.
The term that describes the combined resistive forces in an AC circuit is: resistance reactance impedance.
The basis for transformer operation in the use of alternating current is mutual: inductance capacitance reactance.
The opposition offered by a coil to the flow of alternating current is called (disregard resistance): impedance reluctance inductive reactance.
Capacitors are sometimes used in DC circuits to: counteract inductive reactance at specific locations smooth out slight pulsations in current/voltage assist in stepping voltage and current up and/or down.
Diodes are used in electrical power circuits primarily as: cutout switch rectifiers relays.
In a P-N-P transistor application, the solid state device is turned on when the: base is negative with respect to the emitter base is positive with respect to the emitter emitter is negative with respect to the base.
In a N-P-N transistor application, the solid state device is turned on when the: emitter is positive with respect to the base base is negative with respect to the emitter base is positive with respect to the emitter.
Typical application for zener diodes is as: full-wave rectifiers half-wave rectifiers voltage regulators.
