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।

Good knowledge, sir thanks
Welcome
Bahot achhi knowledge hai sir thanks
thanks
Bhuth achi tarah samjaya hai sir ji thanks ,
thanks
Explained in an excellent way
Thanks a lot
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
आपने बहुत ही सरल शब्दो मे समझाया आपका मैथर्ड बहुत ही मधुर है जिसके लिए कोट-कोटि प्रणाम
thanks
Very nice sir. Sir ek video outdoor dc moter ko 220 volts sey kaisey chalay ये circutt बना कर samjhaye plz. 😊
Sir triac par video banaye....
unbelivable explaination super sir
Super Excellent Teaching Sir.....😊😊😊
So nice of you
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
Very nice explain sir ji.❤❤❤
Thanks and welcome
Sir aapko koti koti naman..........
thanks , pls subscribe our channel for more updates
Thanks sir for your details explanation
Very knowledgeable video sir ji.
Beautiful explaints.resistor.pull up
Pul down helpful nice video best teacher
Glad you liked it
Very good explanation
Vivek sir your great👍👍👍
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
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
Bahuth bahuth dhanyawad sir
thanks
Very nice teacher
Thank you!
Good
Very nice sir ,thanks for concept clearing 🙏
Always welcome
Verey nice sir
Very interesting video
👍👍v good
Very good explanation sir
Thanks and welcome
Excellent thanks
Nice teaching sir
Thanks and welcome
Thanks sir lajawab
Ssr solid state relay par vedio banaya sir aur kahan use hota hai pls.
thanks
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
Great
thanks
Good knowledgeable video
So nice of you
Very good information sir ❤❤❤❤❤❤
Thanks and welcome
Sir please Next video IGBT 😊
Very good class sir.
Thanks and welcome
Sir pfc power supply ka detail me video banao🙏 jis me har section ka alag lecture ho.
thanks
Sir zener diode pe video banaye or breakdown voltage ke bare me bataye
Very nice explain
Thanks for liking
Thanks sair
thanks
Ak igbt ki datasheet kese understand kare is pae video ho jaye youtube par kuch kash nahi hai
Nice explanation
Thanks for liking
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
Sir please make video on inverter Compressor
How to know which compressor should connect to the inverter PCB for testing
ok ji thanks
MCU me bahut jagah se alag alag kam k liye ak sath alag alag volt aata hai kya ?
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
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.
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😊
Jay hind sir
thanks
Very nice ❤sir
So nice
Very nice information sir
Please tell us my you applied resistor near to mcu.
Nice sir❤❤
So nice
Tric par jaroor banaen plese
ji
Mitsubishi electric inverter split AC PCB board SMPS ke bare me bataye sir
ok ji jald banayenge
Sir ham chahte hai ki aap 555ic par ek video bnaea
Sir ji register ground posstive me lage hone per shprt kyo nahi hota. Please bataye.
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
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
गुरु जी धन्यवाद
Pulz की ful foam Pulz wirdth Modulation होती है क्या सर इसको भी थोड़ा एक्सप्लेन करो कृपया
thanks
Kia bata rahe hai sir hardware ya software program ic kese work karti hai
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
