Electrical systems questions and correct answers

The electrical system includes everything that operates electrically with the exception of the ________ - correct answers Magnetos The electrical system provides ______ to the airplane and its controls - correct answers power An electrical system consists of: - correct answers Storage battery, master switch and battery solenoid, starter motor and solenoid, generator (alternator in the Zlin), voltage regulators, bus bar, and circuit breakers. Is the electrical system in the Zlin A/C (alternating current) or D/C (direct current) - correct answers Direct current Is the Zlin's electrical system 12V or 24V? - correct answers 24V To complete the circuit between the battery and the electrical system a battery _______ is incorporated which is activated by the _______ _______. - correct answers solenoid master switch What is a solenoid? - correct answers Acts as a switch that connects the two ends of the electrical system together. When the solenoid is turned on it retracts, connecting the electrical system allowing current to pass. When the master is turned off it is pushed out with the use of a spring to break the connection. This video explains it very well The purpose of the starter motor is to? - correct answers turn over the engine so that it will commence to operate. What happens when you turn the ignition to start on the airplane? - correct answers The start part of the switch will initiate a solenoid that allows current to travel to the starter to turn the engine over. Does the zlin have an alternator or generator and why? - correct answers Alternator, and it is lighter and simpler, it also operates at higher speeds. What is the purpose of the alternator? - correct answers Provides current to the electrical system and recharges the battery. What is the purpose of the voltage regulator? - correct answers Prevents the alternator from over-loading the system and prevents the battery from overcharging. What is the bus bar? - correct answers The bus bars take the current from the alternator or battery and passes them through the various circuit breakers and out to various electrical circuits to components. What is a circuit breaker? - correct answers Protects the components of the aircraft from too much voltage/current and short circuits. If a breaker pops out, it is common practice to push it back in to reset the system, if it pops out again it is advised not to push it back in, because this can cause an electrical fire. For electrical instruments that aren't automatically turned on by the master switch, should they be kept on or off when starting the engine - correct answers off The ammeter is used to indicate - correct answers the amount of electrical current being produced, measured in amps If the ammeter is pointing the needle towards the - that means the electrical system is getting power from the alternator/battery - correct answers battery How do generators work? - correct answers How do alternators work? - correct answers How do batteries work? - correct answers How many amps does the Zlin electrical system provide? - correct answers 60 Amps What are the different symbols and what do they represent in a electrical schematic? - correct answers
