Page 9 of 512. Basic Circuits NCATT Training Standard Level (2b)(b) Troubleshooting CircuitsObjective:The student will determine procedures for troubleshooting basic electrical circuits.Content – Troubleshooting Circuits:Explain that troubleshooting is the ability to diagnose and repair a defective circuit. There aredifferent techniques to use while troubleshooting a circuit depending on the type of circuit beingtested. The most common problems encountered while troubleshooting circuits are the following:• Open resistors or contacts.• Shorts between conductors.Demonstrate to the student how to test the following circuits for defects using a multimeter.• Series Circuits• Parallel Circuits• Complex Circuits with a Voltage Drop• Resistors in Series Circuits• Resistors in Parallel Circuits• Bridge Circuits3. Basic Circuit Calculations NCATT Training Standard Level (B)(a) DCObjective:Identify the relationship of basic facts and state general principles for DC circuit calculations.Content – DC Circuit Calculations:Explain how Mathematics is an integral part of electronics by using formulas based on Ohm’sLaws and Kirchhoff’s Laws to show the relationship between the following terms:• Volts (V)• Ampere (A, amps)• Ohm (Ω)• Watts (W)Copyright © 2008 by the National Center for Aircraft Technician Training.

Page 10 of 513. Basic Circuit Calculations NCATT Training Standard Level (B)(b) ACObjective:Identify the relationship of basic facts and state general principles for AC circuit calculations.Content – AC Circuit Calculations:Explain the formulas used in AC circuit calculations with reference to the following terms:• Phase angle—See Basic Terms/Alternating Current (AC).• Frequency—See Basic Terms/Alternating Current (AC).• Capacitive Reactance (X C )—See Basic Terms/Alternating Current (AC).• Inductive Reactance (X L )—See Basic Terms/Alternating Current (AC).• Power Factor—See Basic Terms/Alternating Current (AC).• Period—Amount of time for one complete cycle of oscillation to take place.• Peak Voltage—Voltage measured from zero voltage to the maximum number of voltsgenerated.• Effective Value—Value of sine-wave alternating current needed to produce the sameamount of heat as the value of the direct current.• Inductance—Electrical characteristic of a conductor. Inductance causes voltage to beproduced when it is cut or crossed by lines of magnetic flux. Inductance causes thecurrent to lag the applied voltage.• Resonance—Electrical characteristic of a conductor. Resonance occurs in an electricalcircuit when the inductive and capacitive reactances are equal.• Capacitance—Electrical characteristic of a conductor. Capacitance is the amount ofelectrical charge that can be stored in a capacitor under a given amount of electricalpressure (voltage). Capacitance causes the current to lead the applied voltage.• Reactance—Electrical characteristic of a conductor. Reactance is opposition to AC flowby coils and capacitors. Values are given in ohms.• Impedance (Z)—See Basic Terms/Alternating Current (AC).• True Power—See Basic Terms/Alternating Current (AC).• Apparent Power—See Basic Terms/Alternating Current (AC).3. Basic Circuit Calculations NCATT Training Standard Level (2b)(c) DC/AC MeasurementObjective:Determine procedures for calculating basic DC and AC measurements.Content – DC/AC Measurement:Explain the advantages and disadvantages of DC/AC measurement. Emphasize the problemsassociated with improper use and storage of the meters, as well as safety issues. Explain anddemonstrate how to use the following meters with an emphasis on which meters work best forvarious measurements and tests.Copyright © 2008 by the National Center for Aircraft Technician Training.
