Standard electrode potential ka cell EMF formula yaad rakh: E°cell = E°cathode - E°anode. Sign sahi rakhne ka simple funda hai: anode woh hai jo zyada negative potential wala hai, oxidation wahin hota hai. Par engineering ke exams mein, sirf formula ratne se kaam nahi chalta — maine apni gym ki EMI chukane ke liye ek ledger banayi hai, har mahine aane jaane waali rashi ka hisaab. Uski tarah, anode-cathode ko bhi "kaun deduct hoga, kaun add hoga" samajh ke likho, tabhi sign galati nahi hogi.
