thanks now i am more clear abt emf.

Hi, When coil is excited with ac because of varying nature of current ,flux of varying nature will be developed in coil and because of varying flux emf will induce in coil. what will happen if coil is excited with dc? intially cureent will increase from zero to maximum and is...

what happens if AC is applied to a capacitor? I am able to understand that ,For 1st half of the cycle,i.e for +ve cycle, during the voltage rise from v0 to vpeak, the capacitor charges, and during the voltage drop from vpeak to v1 the capacitor discharges.Let me know if this is true. I...
