AT 202 EXAM 1 STUDY GUIDE 2025/26 QUESTIONS WITH COMPLETE SOLUTIONS.
Volt - (ANSWER)Electrical unit, used to measue power (elecric potential).
What electromotive force is
Measured in volts
EMF - (ANSWER)Elecromotive force: measured in volts
The measurement of the energy that causes current to flow through a circuit
Watt - (ANSWER)the SI unit of power, equal to one joule per second. Also one watt= one ampere with
volotage of one volt
What is electromagnetic induction, and what three things are needed for it? - (ANSWER)Electromagnetic
induction is when electrical energy is transferred through a magnetic field, essentially creating voltage
by pushing a conductor through a magnetic field.
1. Magnetic Field
2. Conductor
3. Motion
What is polarity? - (ANSWER)the relative orientation of poles; the direction of a magnetic or electric
field. (Which way its flowing)
What kind of generator and electrical bus are used on the A380? - (ANSWER)
What kind of generator and electrical bus are used on the B747? - (ANSWER)Split/Parallel System on
B747-400
Parallel on normal B747
, AT 202 EXAM 1 STUDY GUIDE 2025/26 QUESTIONS WITH COMPLETE SOLUTIONS.
What kind of generator and electrical bus are used on the B727? - (ANSWER)Parallel Bus System
How many KVA is 2,562 volt amps? - (ANSWER)25.62 KVA (divided by 1,000)
Why do we use flux when soldering? - (ANSWER)It prevents oxidation
Wire gauges? - (ANSWER)Bigger number = smaller wire
Smaller number = larger wire
What are the three ways we can manipulate the strength of an electromagnet? - (ANSWER)1. The
strength of the magnetic field
2. The speed of the rotation
3. The number oif coils
What are the three common methods for starting the engine on a turbine aircraft? - (ANSWER)1. Huffer
Cart
2. APU bleed air
3. Starter Generators
Isulator - (ANSWER)No room for free electrons (won't allow current)
Plastic, air, glass, teflon
Conductor - (ANSWER)Room for free electrons (will allow current)
