As we know that SCR has three terminal like : i) Anode (A)
ii) Cathode (K)
iii) Gate (G)
To turn ON SCR there is only two ways : 1) Increase the forward voltage beyond the break over voltage.
2) By giving positive triggering gate pulse to the SCR.
The firing potential of SCR is applied to the Gate terminal of the SCR.

Garmiyo ke season aate hi hamaare mann mein kuch thanda ho jaya aise sab khayaal aate hai. aisa sochana ye toh hamaare liye bilkul natural hai. Actually garmiyo ke season mein hum jyaada kar ke thande-thande padarth khaana pasand karte hai. Jaise ki ice-cream, kulfi, cold drinks, fruit juice aur sabhi prakar ke beverages. Lekin kya aap ko pataa hai, yeh sabhi padarth ko thanda karne ke liye usse fridge mein rakhaa jaata hai.
Garmiyo ka season chaalu hua nahi ki hum fridge ke thande-thande paani peene lagte hai. Thanda paani peene ke baad hamaara pyaas bujha toh jaata hai. Lekin kya aapko pataa hai fridge ka paani hamaare sehath ke liye bilkul achha nahi hota hai.
1) Kya aap ko pataa hai fridge ka thanda paani peene se hamaaraa shareer bahut aalsi jaisa mehsus karta hai.
2) Hamaara digestive system bahut hi weak hota jaata hai.
3) Fridge ka thanda paani peene se hamaaraa shareer uss thande paani ko garam karne mein bahut jyaada urjaa kharch kartaa hai, aur kya aapko pataa hai wo urjaa aati kahaa se hai, wo urjaa hamaare blood se aati hai. Iss ka matlab yeh hua ki jo blood baaki sab organs ko supply mein kaam aati thi wo blood aap ke thande paani ko garm karne mein lag gaya. Aur maanlo aisa hi chalta rahaa toh ek din aisa aayega ki aapke jitne bhi organs hai wo sab dheere-dheere jawab dete jaayenge, iss ka matlab ki wo kharab hote jaayenge, kyun ki aap ka blood ka supply ab uss organs ko nahi mil rahaa hai jiss organs ko blood ki supply ki jarurat thi.
3) Thande paani peene se aap ko constipitation ki bimaari toh aani hi hai ye paakaa hai. Iss constipation ko hindi mein hum kabj ke naam se jaante hai.
4) Aur yahaa tak aap jaan lijiye jo log jyaada fridge ka paani peete hain unn logo ko latrin jaldi nahi utarta hai. Issliye wo log bathroom mein ghanto-ghanto news paper lekar baithe rahatein hai.
Isse ye saaph ho jaata hai ki agar hum fridge ka paani peete hai, toh ye maanlo ki hum marne ke kagaar par hai.
Agar aap ko thanda paani peena hi hai toh aap matkke ka paani pee sakte hai. Ye bahut hada tak safe hota hai. Darasal matkke ka paani naturally normal temperature hota hai, jisse hamaaraa shrareer usse aasaani se digest kar letaa hai. Aur waise bhi aap sab jaante hai ki matkka ek eco-friendly natural cooling substance hai, jo paani ko normal taarike se thanda karta hai.
Agar hum baata dein ki Fridge jo hota hai yeh eco-friendly nahi hota hai. Agar aapke ghar mein fridge hai toh jaan lijiye ki wo eco-friendly nahi hai. Kyun ki fridge constantly ek baut khatarnak gas release kartaa hai aur wo hai Chloro-Flouro-Carbon (CFC). Chloro-Flouro-Carbon (CFC) Hamaare environment ke liye bahut hi dangerous hota hai, ye gas global warming ko barakarar rahne mein madat kartaa hai. Aapko hum bataa dein ki global warming usse kehte hai ki jab hamaare environment ka temperature dheere-dheere badhane lagataa hai, hamaare normal temperature se.
Agar hum matkke ka paani peeyenge toh hamaara sehath ke saath-saath hamaara environment bhi fresh and polluted free rahega.

Hamein haftein mein ek baar apne-aap ke liye jarur kuch time dena chahiye. Kuch time dena ka matlab yeh hai ki hamein haftein mein ek baar kisi ek adventurous jagahh par jarur jaana chahiye. Jab hum aisi kisi adventurous jagahh par jaayenge toh hamein bahut achha mehsus hoga. Hamein aisa lagega ki chalo aaj kuch nayaa aur kuch alag sikhane aur dekhane ko milega. Mera kehne ka matlab yeh ki hamein uss jagahh par jaanaa chaahiye jahaa pahaad ho, jahaa nadiyaa ho, jahaa paani ke jharne ho, jahaa khuli jagahh ho, kuch aisa jagahh jahaa par aas-pass koi ghar na ho.
Jab aise jagahho par hum ghumne ke liye jaayenge toh hum apne-aap ko bahut hi halka mehsus karenge. Hamein aisaa lagega ki humaare sar par se bahut hi badaa bojha utar gayaa hai. Uss jagahh ki khuli hawaaye jab hum apne andar lenge toh hamaare shareer ka oxygen level badhega, aur hum apne-aap ko bahut aaraam feel karenge.

Chaliye mein apne baare mein bataataa hun, mein mumbai mein lagbhag 5 saal ho gaye hai, lekin mai aapko sab kya bataau ab tak gaon nahi gayaa. Mujhe bahut mann hota ki iss saal gaon chalaa jaau lekin kya karu padhaai ke wajase gaon nahi ja paata hun. Aap sab soch rahe honge ki aise kaise nahi gaon jaa saktaa hun. Actually mein jab 9th standard pass hua tab meine apne ssc board ke liye tayeyaari shuru kar diya, iss wajase mai uss saal gaon nahi jaa sakaa. Aur jab mai ssc pass hua tab fyjc ka online form bharna padaa phir iss ke liye tayeyaari shuru kar diya, jaise hi fyjc pass hua toh meraa 12th ka tension sar pe aa gayaa. Phir kya 12 pass hone ke baad 3 saal abhi polytechnic course kar rahaa hun aur soch lijiye ab tak mai gaon nahi gayaa.
Yehi experience aap sab se share karnaa chahataa tha, ki aap bhi meri tarahh apne khush bhari zindagi ko yu hi jaane na dein iss din-bhar ki zindagi mein se zara sa time nikaal kar kahi adventurous jagahho par jaakar aayein. Isse aapko junun aur kaam kar ka motivation level boost ho jaayega. Aap sabhi ko mai yehi kehna chahunga, ki aap sab mere jaise galti naa kare kyun mujhe koi idea nahi tha ki adventurous jagahh ghumne se kitna achha mehsus hota hai.
