REVIEW QUESTIONS
1. RT-40 AND RN-50 type Voltage relays where and what for used?
2. Electromagnet of relays work principle how?
3. Maxim and minimum current relays between difference from what consists of
4. What for RT-40 type of the relay when the coils are connected in parallel work until two times increases?
5. Current and tension of relays Back to coefficients how is determined?
