Yaar, displacement current toh woh imaginary current hai jo Maxwell ne socha tha, changing electric field ke wajah se. Isne Ampere's law ko thik kiya capacitor charge hote waqt, kyun ki beech ke gap mein koi actual current nahi tha, phir bhi magnetic field banti thi. Maine yeh chapter last week padha tha aur meri didi ke parlour ke AC ki humming sunte sunte socha – uska changing electric field bhi kuch current jaisa kaam karega kya? Par phir yaad aaya, agar theory sahi hai toh mere ghar ke meter ka bill itna kyun aata hai bhai!
