EAWS Avionics exam 2024 with 100% correct answers

List the ratings which comprise the Avionics Division. correct answersAT, AE Name three requirements of a basic electrical circuit. correct answersPower Source (Battery), Switch, Load (Light Bulb) Describe the direction of current flow. correct answersElectron movement is from a region of negative potential to positive potential Explain how the following circuit protectors work. correct answersa. Fuses - Bare wire between two contacts which melts in the event of over current condition b. Circuit breakers - Switch designed to automatically disengage to break the connection between two contacts, in the event of an over current condition can be reset. Define the following terms: correct answersa. Alternating Current - Current which constantly changes amplitude and direction b. Direct Current - Current traveling in one direction only. c. Voltage - The force that allows current to flow, measured in Volts. d. Current - Movement of an electron through a conductor, measured in Amps. e. Resistance - Opposition a device offers to the flow of electrons, measured in Ohms. f. Frequency - The number of complete cycles per second existing in any for of wave motions, measure in Hertz. Define and describe Ohm's Law. correct answersElectrical current (I) flowing through a given resistance (R) is equal to the applied voltage (E), divided by the resistance. Used for calculating circuits. Explain the difference between NC and NO contacts on a switch. correct answersNC - Normally Closed, switch is closed and allows flow of electricity until actuated. NO - Normally Open, switch will not allow electricity to flow until actuated.
