What is the unit of measure for electrical current
AMPS
Define Resistance
impedes the amount of voltage or AMPS in a circuit
Define Ohm’s Law
current through a conductor between two points is directly proportional to the voltage
Define Frequency
number of complete alternations per second of an AC circuit
Define Electrical Bus
central point at which either AC or DC voltage is distributed throughout multiple systems
Define Circuit Breakers
push-pull type, over current protection device that is resettable
Define Fuse
an overcurrent protection device that is for one-time use only
Define Relay
an electrically actuated switch used to control the distribution of electricity in a circuit
State the output of the Integrated Drive Generator (IDG)
115/200 VAC
State the two batteries utilized on the aircraft
- Main Battery
- Aux Battery
State the purpose of the transformer rectifier units (TRU’s)
converts power to be utilized by the airplane systems that require DC power
