इस वीडियो में हम आपको बताएँगे की Pull-Up Resistor और Pull-Down Resistor कैसे काम करता है
Pull-Up Resistorकार्य:
Pull-up resistor का उपयोग तब किया जाता है जब एक पिन को उच्च (high) वोल्टेज पर रखना होता है जब कोई सक्रिय इनपुट न हो। इसे वोल्टेज स्रोत (जैसे 5V) और पिन के बीच कनेक्ट किया जाता है।कैसे काम करता है:जब इनपुट पिन डिसकनेक्टेड या निष्क्रिय हो, तो यह resistor के माध्यम से उच्च (high) वोल्टेज पर खींच लिया जाता है।जब इनपुट पिन को सक्रिय रूप से निम्न (low) वोल्टेज से कनेक्ट किया जाता है, तो यह पिन को निम्न (low) वोल्टेज पर खींच लेता है और pull-up resistor से थोड़ा करंट बहता है।
Pull-Down Resistorकार्य:
Pull-down resistor का उपयोग तब किया जाता है जब एक पिन को निम्न (low) वोल्टेज पर रखना होता है जब कोई सक्रिय इनपुट न हो। इसे पिन और ग्राउंड (GND) के बीच कनेक्ट किया जाता है।कैसे काम करता है:जब इनपुट पिन डिसकनेक्टेड या निष्क्रिय हो, तो यह resistor के माध्यम से निम्न (low) वोल्टेज पर खींच लिया जाता है।जब इनपुट पिन को सक्रिय रूप से उच्च (high) वोल्टेज से कनेक्ट किया जाता है, तो यह पिन को उच्च (high) वोल्टेज पर खींच लेता है और pull-down resistor से थोड़ा करंट बहता है।

Bhuth achi tarah samjaya hai sir ji thanks ,
Bahot achhi knowledge hai sir thanks
thanks
Sir triac par video banaye....
Explained in an excellent way
Thanks a lot
Very nice explain sir ji.❤❤❤
Thanks and welcome
Good knowledge, sir thanks
Welcome
unbelivable explaination super sir
Sir ji kya samjane ka tarikha dil se salute sir bahut din se confuse thaa aj clear ho gaya tq so much 🥰 sir love from odisha❤
thanks
Sir aaj samaj main aya keh resistor kia kaam karta hai aur circuit main kaisy use karty hain. Thanks for delivering the valuable knowledge.
thanks , pls subscribe our channel for more updates
@@multitechinstitute Done
Sir aapko koti koti naman..........
thanks , pls subscribe our channel for more updates
Sir bahut achhe tarike se aap ne samjhaya sir me aap ko request karta hu ki ek bar induction cooker ka pcb ka video banaiye
thanks
Beautiful explaints.resistor.pull up
Pul down helpful nice video best teacher
Glad you liked it
Very good explanation
Very knowledgeable video sir ji.
Very nice teacher
Thank you!
आपने बहुत ही सरल शब्दो मे समझाया आपका मैथर्ड बहुत ही मधुर है जिसके लिए कोट-कोटि प्रणाम
thanks
Thanks sir for your details explanation
Vivek sir your great👍👍👍
Nice teaching sir
Thanks and welcome
Verey nice sir
Very nice sir ,thanks for concept clearing 🙏
Always welcome
सर आप भगवान है हमारे लिए आज तक मैं यही समझता था कि प्लस और माइनस टकराएग तो वहां सर्किट घोस्ट हो जाएगा
😮😮😮😮😮😮😮😮😮😮😮😮😮😮😮😮😮😮😮😮
thanks , pls subscribe our channel for more updates
Good
Very interesting video
Very good explanation sir
Thanks and welcome
👍👍v good
Sir MCU k bare me detail se btaae ...pls
Sir aap k coaching pr jaldi aaunga courec k liy
thanku pls call or whatssap on 9716994446
Very good information sir ❤❤❤❤❤❤
Thanks and welcome
Sir please Next video IGBT 😊
Good knowledgeable video
So nice of you
Thanks sir lajawab
Ssr solid state relay par vedio banaya sir aur kahan use hota hai pls.
thanks
Very good class sir.
Thanks and welcome
Sir zener diode pe video banaye or breakdown voltage ke bare me bataye
Excellent thanks
Great
thanks
Sir pfc power supply ka detail me video banao🙏 jis me har section ka alag lecture ho.
thanks
Very nice explain
Thanks for liking
Nice explanation
Thanks for liking
Ak igbt ki datasheet kese understand kare is pae video ho jaye youtube par kuch kash nahi hai
Sir kissi be trs ke base ko low or high karna ho to kesse karen es pe video banaye
Very good Sir
Thanks and welcome
Top.1.
Very good method
Thanks for liking
MCU me bahut jagah se alag alag kam k liye ak sath alag alag volt aata hai kya ?
Nice sir❤❤
So nice
Thanks sair
thanks
Very nice ❤sir
So nice
Jay hind sir
thanks
Tric par jaroor banaen plese
ji
Sir please make video on inverter Compressor
How to know which compressor should connect to the inverter PCB for testing
ok ji thanks
Video ka last point infomativ tha starting ma ya to samajh aya ki rasistor kasa Kam kar rha hai par ya nahi samajh aya ki wo lga kyu Raha hai MCU par jab vha pahla sa hi volt 0 hai😅 par vo likaj ko rok rha hai😮kya ma sahi hu sir😊
Nice sir.
But ek quest hai.
Buzzeer ka dusra end 0v per bhi hoga to dikkat kya hai? Bina switching ke to -ve aayega hi nhi.
Pls reply.
Very nicely and wisely explained sir, thanks a lot.
if 5 v + ve line attached with some cercuit just to enable once, how will we calculate values of series registor and pull down register... pl. Explain.
Thanks
Very nice information sir
Please tell us my you applied resistor near to mcu.
Sir ham chahte hai ki aap 555ic par ek video bnaea
Mitsubishi electric inverter split AC PCB board SMPS ke bare me bataye sir
ok ji jald banayenge
Sir ji register ground posstive me lage hone per shprt kyo nahi hota. Please bataye.
Kia bata rahe hai sir hardware ya software program ic kese work karti hai
Sir transformar pe video bnaye please
thanks , pls subscribe our channel for more updates
L.e.d. सर किती किलो का रजिस्टर लगाना चाहिए dc48v. Chahiye 12v रजिस्टर किती किलो का लगाना चाहिए
Sir resistanse jo hai o ampere ko drop karta hai ,volt ko??
MCU koi ampere ke rukh me nahi jana voltage ke rukh me jata he
गुरु जी धन्यवाद
Pulz की ful foam Pulz wirdth Modulation होती है क्या सर इसको भी थोड़ा एक्सप्लेन करो कृपया
thanks
Mcu ki barhi mhi banwo
Hello Sir
Ac Pcb Course ko Koi 499 mein bech Raha hai
Aor Aap 15000 Mein 😆😆
yes sir aap 499 wala join kijiye
mai iphone chalata hu aur aap shayad real me ya oppo use karate hai but dono phone se bat hoti hai aur call v
tho paise quwality ka liya jata hai
Good
Thanks
