Asal baat sirf yeh nahin hai ki current kitna badalta hai - voltage ke muqable current kab badalta hai, yahi LCR graph ka raaz hai. Shrinkhala wale LCR circuit mein teeno saath hote hain, isliye kul timing is par nirbhar karti hai ki L ka asar zyada hai ya C ka. L ka AC ke badlav ka virodh X_L kehlata hai; C ka virodh X_C. Agar L haavi ho, to current peeche rehta hai; C haavi ho, to current aage. Yani poore circuit ka graph, kisi ek hisse ke niyam se tay nahin hota. Ek khaas sthiti mein donon asar barabar ho jaate hain: X_L = X_C. Ise resonance kehte hain - yani L aur C ka virodh ek-doosre ko santulit kar deta hai. Tab phase difference shoonya hota hai aur voltage-current ki laharen phir saath chalti hain. Tay source voltage par current bhi adhiktam hota hai. To graph mein pehchaan saaf hai: resistor mein saath, inductor mein current peeche, capacitor mein aage - aur resonance par phir saath.
