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.
Yes, an example is an automobile's ignition coil, which is energised from the battery, via the contacts within the distributor. The contacts open and close, supplying the ignition coil with pulsating current.
A transistor is primarily used to amplify or switch electronic signals and can indeed be utilized in circuits that convert pulsating DC into another form of pulsating DC. However, its primary function is not to transfer but to control and modulate signals. In applications like switching power supplies or pulse width modulation (PWM) circuits, transistors can effectively manage and modify pulsating DC voltage. Thus, while they can work with pulsating DC, the term "transfer" may not fully capture the transistor's role in these applications.
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
The frequency of pulsating DC, often referred to as pulsating direct current, is determined by the rate at which the voltage alternates between its maximum and minimum values. In a typical scenario, this frequency corresponds to the frequency of the alternating current (AC) supply from which it is derived, such as 50 Hz or 60 Hz. Pulsating DC can be generated through rectification of AC, leading to a waveform that oscillates but does not alternate in polarity. The frequency of the pulsating DC is thus defined by the rectification process and any filtering applied to the output.
no. because if we use dc source for transformer there will be no production of energy for the secondary side since they are mutually conducted, as the transformer is a static device which can transmite the energy from one circuit to other with out changing the frequency and also there is no movement of the conductors. in order to produce the emf there should be either conductor movement or moving flux so the dc source will produce constant field flux hence there is no production of energy in the secondary side.
I should think not
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
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.

The transformer used in mobile is pulse transformer which operates at very high frequency pulsating DC in order to make charger energy efficient and light weight.
Transformer works with varying flux. DC won't create it. Only AC produce varying flux.
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.
A transformer requires a changing input to generate an output.
Because of how a transformer works. Basically a transformer have a primary and a secondary winding sitting close to each other, with the primary connected to the ac source. Pushing ac through the primary wionding creates a pulsating magnetic field. Pushing a pulsating magnetic field through the secondary winding creates an electric current in it. That current will also be ac, but dependent on the number of turns in the windings it will have another voltage. DC don't give a pulsating magnetic field from the primary winding, and a stationary magnetic field won't generate any electricity in the secondary winding.
No, unless you have a pulsating DC

Not really. Frequency in is frequency out, unless there is some conversion circuit in between, such as a motor-generator set or some kind of inverter. You may (and should) notice, however, that a typical welding transformer is rectifying three phase AC to DC, using a full wave rectifier. This results in a pulsating DC voltage where the ripple frequency is 360hz.
