What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
What is the ripple factor of full wave rectifier?
although the AC signal is rectified the output which we get is the pulsating DC which is not desired because many appliances wok on plain DC voltage . The pulsating DC can be viewed as AC + DC component of the signal ripple factor of a rectified circuit is the ratio of AC component of signal to the DC component of the same rectified output signal. higher the ripple factor says that the signal is not smooth so lesser is its application. the components used to smooth these type of signals or to remove the 'ripple voltage' as called filters
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.
Characteristics of a capacitor?
Block DC components and pass AC component
Why the filter used in rectifier circuit?
Filter capacitors smooth out the pulsating DC. Without the capacitors, the pulsating DC drops to zero at the AC crossing point, unless it is a three phase rectifier. Sometimes, that is sufficient. Sometimes, they are followed up with a regulator circuit that further stabilizes the DC.
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
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 difference of DC and pulsating DC?
DC: constant current in the forward directionPulsating DC: An AC signal which has it's negative components blockedA: The terminology applies to a VALUE of DC being interrupted by its absence periodically or random
What component of a motor changes induced AC voltage into a pulsating DC?
its commutator..which converts ac produced by and motor to pulsating dc ... more the commutator divide more accurate dc..means less pulse in dc
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
How do you conver ac power into pulsating DC What devices you need?
rectifier circuit convert ac to dc signal
What is the function of a rectifier diode?
A rectifier can convert AC to pulsating DC.
What is the operation of a rectifier?
The operation of a rectifier is to conver a AC signal to a pulsating DC signal
When measuring electrical components how can you tell if it will be AC or DC?
Typically DC is what you get in a battery and AC is what powers your house.
Why electronics device work only in dc?
Obviously you have not yet begun the AC circuit analysis class. Wait a few quarters.Some components are normally used with DC, some components are normally used with AC, but most components can be used with both DC and AC.
Why diodes are used after center tapped transformer in dc to ac inverter?
Diodes are used after a center-tapped transformer in a DC to AC inverter to rectify the alternating current (AC) output of the transformer into pulsating direct current (DC). This rectified voltage is then smoothed using filters to produce a more stable DC waveform. The diodes act as one-way valves, allowing current to flow in only one direction, thus converting the AC voltage into a pulsating DC voltage.
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.
