I have an instrument that involves an electronic circuit. In circuit there is a PTC B754 (having operating voltage 230V). PTC is already damaged and same PTC is not available in market. Now what can i do to solve that problem.
2658if a PTC having operating voltage 230V is not available then Can we short the circuit where PTC inserted or anybody having other solution. if yes, please reply hurry.

engineer rrb electronics send me plz sadiksharif@gmail.com how to design an ups and battery connections for ups . Iwant the old question paper for J.E(Tele.Signal). For what a triggering circuit is provided in a cro? Why slew rate is not infinite in ideal op-amp? What is the turn-off time for converter grade scrs and inverter grade scrs? We are facing the problem of communication failure between seimens drives and ABB DCS. Between drives and DCS on RLM -01 module for communication purpose. We found red blinking i.e error blinking in RLM -o1 module. So we replaced with new one but after one month same problem again came. So again we installed old RLM-01 module. Now also RED blinking is coming but sometimes drives are not tripping. What will be the cause for this problem? How many mosfet switches are there in dynamic ram? Explain what is the main application of scr in electronic field as well as in software field?
