Q1:- When both synchro transmitter and receiver rotors are displace from zero by the same angle they are in 
Q2:- capacitor start capacitor run motor is generally coupled with the air conditioner compressor because it
Q3:- A capacitor start capacitor run motor has two capaciotrs. when the motor is started
Q4:- By pushing and pulling the rotor shaft a motor can be checked for
- correspondence
 - phase
 - error
 - unbalanced field synchronism
 
Q2:- capacitor start capacitor run motor is generally coupled with the air conditioner compressor because it
- takes low starting as well as running current
 - is cheaper
 - is quit in operation
 - does not require any maintenance
 
Q3:- A capacitor start capacitor run motor has two capaciotrs. when the motor is started
- only one of the capacitors is in circuit
 - both the capacitors are circuit and are connected in parallel
 - both the capacitors are in circuit and are connected in series
 - both are in series
 
Q4:- By pushing and pulling the rotor shaft a motor can be checked for
- end play
 - side play
 - firm mounting
 - free shaft movement
 
ANSWER:-1

- bar to bar
 - voltage drop
 - growler
 - all of the above
 
ANSWER:-4
