I have a rectifier circuit that I came across in my textbook. I'm concerned with only one specific part of the circuit at the moment. After the source voltage is rectified and arrives at the inductor, what actually smooths out the current? I know that the inductor opposes changes in current and initially the current is rising (along with a changing magnetic field). So when the rising/changing current approaches the inductor a magnetic field is induced in the inductor that opposes the the magnetic field of the current. A voltage/EMF is also induced in the inductor that opposes the change in current. As soon as the current reaches its peak and begins to decrease, The magnetic field/Voltage/EMF induced in the inductor is reversed and the inductor tries to aid the now decreasing current. But how has this processed smoothed out the current? Is it the EMF that reacts against the current initially pushing against it and then pushing with the current that causes it to smooth out?
