Jab kai taar ek jagah milte hain, to current aakhir jaata kahan hai - kya kuchh hissa wahin khatm ho jaata hai? Ise pipes ke junction jaisa samajhiye: paani andar aata hai, to utna hi baahar jaata hai. Circuit ke aise bindu ko node kehte hain. Yahi Kirchhoff's Current Law, yaani KCL hai: node mein aane wala kul current, baahar jaane wale kul current ke barabar hota hai. Maan lijiye 2 ampere aur 3 ampere node mein aa rahe hain, aur ek shaakha se current baahar ja raha hai. Sameekaran: 2 + 3 = I. Isliye I = 5 ampere. Disha ke teer vishleshan ke liye chune jaate hain; uttar negative ho, to asli disha ulti hai. To current node par gaayab nahin hota. Jaise pipe-junction mein pravaah bana rehta hai, vaise hi aadarsh node mein charge jama nahin ho sakta. Har ampere andar aayega, to baahar jaayega.
