What is a common cause of damage to solid-state components and/or integrated circuits?
Electro-Static discharge (ESD) from the human body during handling.
15
Describe magnetism.
An objects property which attracts metallic substances.
15
What is the difference between permanent and temporary magnets when the external magnetizing force is removed?
Permanent magnets retain their magnetism. Temporary magnets rapidly lose magnetism.
15
What makes up an electrical circuit?
A source of electrical energy, a resistance(load) and conductors (wires).
15
What law governs the basic study of electricity?
Ohm’s law.
15
What are the basic elements of Ohm’s law?
Voltage, Resistance , Current.
15
What change occurs in a D.C. (direct current) circuit when applied voltage is increased & resistance remains constant?
Current increases.
15
How do you express Ohm's Law as an equation?
.
15
Scientifically, power is measured in:
Watts.
15
What are some common methods electrical energy can be produced?
Pressure (PIEZOELECTRIC MATERIALS), Chemical (BATTERY), Thermal (THERMOCOUPLES), Sun Light.
15
What Law is relevant when it comes to voltage?
Kirchoff ́s law.
15
Explain Kirchoff's Law.
.
15
Three types of D.C. Electrical circuits:
Series, Parallel and Series/Parallel. (complex)
15
What types of circuits do A&Ps encounter on an aircraft?
A combination circuit, series-parallel.
15
Compare AC & DC circuits in aircraft.
DC flows constantly in 1 direction. AC can change direction at/during regular intervals, is lighter and its voltage can be stepped up/down ( with transformer).
