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.
2027if 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.
