Study Notes

Kirchhoff's law states that the sum of currents at a node is zero.
Electrical resistance is denoted by the letter R.
The unit of electrical resistance is Ohm.
A capacitor is a two-pole reactive component that realizes the electrical quantity - capacitance.
The unit of capacitance is Farad.
The characteristic parameter of coils is inductance.
The most important parameters of capacitors are nominal capacity.
The value of a DC electrical quantity remains constant over time.
The unit of frequency is Hertz [Hz].
The voltage in a household network has a standard harmonic waveform with a frequency of 50Hz, while in aviation it is 400Hz.
An electron with a negative charge is located in the outer shell of a semiconductor.
The occupation of a free space (hole) in a semiconductor by other free electrons is called recombination.
The diffusion voltage for silicon has a value of 0.5 to 0.8 V.
Diodes are electronic components that conduct electric current in only one direction (depending on the polarity of the applied voltage).
Transistors are electronic components usually with three electrodes.
Boolean algebra uses disjunction as logical addition.
The logical product equals one when one input variable has a value of 1.
The high transmission speed of the ARINC bus is 100 kHz.
The ARINC 429 protocol word format is 32 bits.
The AFDX bus has much higher data throughput, reliability, and error resistance compared to other data transfer formats such as ARINC 629 and ARINC 429.
The transmission of signals using the ARINC bus is accomplished using two shielded conductors.
The evaluation of signals on the conductors is the responsibility of the ARINC 429 bus.
Which elements belong to the secondary sources of electrical energy? Transformer, inverter, rectifier.

What is the value of the voltage on the terminals of a fully charged aircraft nickel-cadmium battery? 28 V-DC.
Which systems supply the aircraft pneumatic circuit in the traditional concept? De-icing, cabin pressurization, air conditioning system.
Which elements do not belong to the primary sources of electrical energy? Rotary converters.
The aircraft's DC voltage source has a value of 28V and 270V.
Combined contactless generators - starter-generators are primarily used to produce electrical energy in the aircraft's AC power systems.
DC generators do not belong in the auxiliary onboard power sources of electrical energy.
Circuit breakers are electromechanical devices that interrupt and isolate the electrical circuit in case of excessive current and can be reconnected.
The electrical network of an aircraft consists of conductors, connectors, switching, protective, and noise-reducing elements.
Flashing position lights are white and are located at the ends of the wings and at the end of the fuselage.
The internal emergency lighting includes aisle lighting
