DC: constant current in the forward direction

Pulsating DC: An AC signal which has it's negative components blocked
A: The terminology applies to a VALUE of DC being interrupted by its absence periodically or random

What is the pulsating DC frequency?

When AC full wave is rectified into DC by using bridge rectifier .The DC do not actually behave like an ordinary DC and the DC has a constant value .In fact, it is in pulsating form.This is known as Pulsating DC.

What is the function of a commutator in DC generator?

All types of generators induce EMF in sinusoidal wave form. (A.C.) In a D.C. generator the function of a commutator is to convert A.C. EMF into D.C. The commutator rectifies the output that is the alternating current so as to produce unidirectional alternating current (pulsating DC). This reverses the negative polarity current to a positive one so as the output is a pulsating DC.

Can diode work on ac power supply?

diodes conduct electricity in only one direction but as ac change direction in each of its cycle diodes can only conduct half of its cycle which will give u a pulsating dc. but if dc is mixed with ac and if it can put whole of its cycle in positive direction diode can conduct ac. so diodes are usually used to produce dc from ac.

What is the difference between ac ammeter and dc ammeter?

dc ammeter has three connecting pins while ac has four

How do diodes convert ac to electricity to dc?

As such - a single diode cannot do this. It is the way that more than one diode is configured in a circuit that does this. ANSWER : A single diode does indeed convert AC to DC. But it will be a pulsating DC by adding a capacitor it can be DC.

Do transformers work on DC supply?

No, unless you have a pulsating DC

Why use capacitor in circuit?

To smooth the output of the pulsating DC.

What is the difference when selecting a cable between AC and DC current?

AC. is alternating current and Dc is direct current. alternating equivalant to pulsating electricity while direct is a constant draw with little fluxuation.

What component of a motor changes induced AC voltage into a pulsating DC?

A rectifier is used to convert the induced AC voltage into pulsating DC in a motor. This component allows current to flow in only one direction, resulting in a unidirectional flow of electricity.

Why you use filters in your circuit?

we generally use filters to smooth the sharp curves of DC component we get when we rectify AC components the pulsating Dc is not desirable to a no. of devices. These filters are used to make the pulsating DC to a stable one . To be more clear a pulsating DC is viewed as a sum of DC component and AC component these filters actually block the AC components and retain the DC component . so, mainly capacitors and inductors are used to obstruct or pass the dc components respectively

Why capacitor used in rectifier circuit?

To smooth the output of the pulsating DC.

What is the function of a rectifier diode?

A rectifier can convert AC to pulsating DC.

How do you conver ac power into pulsating DC What devices you need?

What is transistor series regulator?

voltage regulator is a component to convert pulsating DC into constant DC.

What device converts dc current to ac current?

A "Rectifier" converts AC current to pulsating DC current.

Do transformer works on pulsating dc?

If the input is pulsating DC, then the output will be pulsating DC. It will not be shaped the same, but it will be close, depending on the frequency and rise and fall time in comparison with the inductive reactance of the transformer.
