PCB के गलत प्रिन्ट जान कर काफी निराशा हुई हमारे जैसे बन्दो के लिए ये एक बहुत बड़ा सबक है साथ ही आप कॉयल पर ड्राई सोल्डरिंग बता रहे थे वो सोल्डरिंग करने का व्यू वीडियो में नही आया या आपसे ही छुट गया अगर ऐसा हुआ तो उसका प्रभाव क्या होगा ? ये बताने की कृपया करना - धन्यवाद
@vccground-hindi
Ай бұрын
वैसे तो गलत प्रिन्ट की समस्या काफी कम होती है, पर फिर भी कभी कभार हो ही जाती है। तो इस बारे में भी ध्यान तो देना ही पड़ेगा। कॉइल की ड्राई सोल्डरिंग मैंने फिक्स कर दी थी। ऐसा न करने पर लोड पर आउटपुट करंट में कमी आ सकती है।

Gate MOSFET me hota hai dost, transistor me Base hota hai. Ye 2.5 ohms ki resistor transistor ke base par lagti hai.
My question is not related with the faults in this power supply. But it is related with use of capacitor which has high voltage values and situated in between ground of input voltage and ground of output put voltage. I think in this board it is placed near input 110/220 voltage selector switch.please enlighten us why it is used and how do we calculate its value? Thanks
