How do inductors smooth 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.

What does an inductor do in a rectifier?

An inductor is used a filter to remove the AC component in the rectified output. Inductors allow DC to pass through them and block AC. Hence they are connected in series with the load resistor in a half wave rectifier so the DC component of the rectified output can reach the load resistor.

How do I make my rectifier smooth?

To smooth the output of the rectifier a reservoir capacitor is used – placed across the output of the reciter and in parallel with the load.

How the output voltage of a rectifier is made smooth by the use of a filter circuit?

When a pulsed voltage appears at the output of the rectifier, it first charges the capacitor, before appearing at the output of the circuit. When the pulse ceases, the excess charge in the capacitor gets pushed out to the output. The result is a more smooth voltage.

Do inductors limit current?

An inductor can limit current BUT ONLY IN an AC circuit. An example is a choke ballast in a fluorescent light fitting.

How do you smooth a DC power supply?

Smoothing is performed by a large value electrolytic capacitor connected across the DC supply to act as a reservoir, supplying current to the output when the varying DC voltage from the rectifier is falling. The diagram shows the unsmoothed varying DC (dotted line) and the smoothed DC (solid line).

What does a smoothing condenser do?

A Smoothing capacitor is a capacitor that acts to smooth or even out fluctations in a signal. The most common and used application for smoothing capacitors is after a power supply voltage or a rectifier. Power supply voltage can sometimes supply erratic and unsmooth voltages that fluctuate greatly.

How do capacitors smooth?

Frequently capacitors are put across the power supply to hold the voltage steady. This works because the more capacitance you have, the harder it is to change the voltage, because it requires more current to do so. In this application, capacitors don’t smooth energy, they smooth voltage.
