Agar circuit mein charge jama hone lage, ya energy gayab ho jaaye, to kya hoga? Traffic intersection mein aane wali cars ka hisaab jaane wali cars se milna chahiye. Circuit mein bhi yahi balance hai. Kirchhoff's Laws manmaane formulas nahin, conservation checks hain. Pehla, Kirchhoff's Current Law, yaani KCL, node par laagu hota hai, woh junction jahan raaste milte hain. Entering current ka total, leaving current ke total ke barabar hota hai. Yahi charge conservation hai: charge node par jama nahin hota. Doosra, Kirchhoff's Voltage Law, yaani KVL, closed loop ke chaaron taraf laagu hota hai. Voltage rises aur drops ko signs ke saath joden, to algebraic total zero hota hai. Yeh energy conservation hai. Voltage khud energy nahin; woh prati charge energy transfer ke antar ko darshata hai. Yaad rakhiye: node mein current balance, loop mein voltage balance. Direction chunen; negative answer ka matlab hai ki direction ulti hai. To jawaab hai: node par charge pile up nahin kar sakta, aur closed loop mein energy na paida hoti hai, na gayab. Yahi Kirchhoff enforce karte hain.
