The start winding circuit in a hermetic motor is interrupted by a potential relay or a current relay because ______ mechanical switch.
a. potential relays or current relays offer more precise and reliable operation than a mechanical switch.
b. potential relays or current relays can respond more quickly to changes in the motor's operating conditions.
c. potential relays or current relays can be easily adjusted for different motor loads and operating conditions.
d. potential relays or current relays require less maintenance and are less prone to failure than a mechanical switch.
