If its a triangular wave, its not DC, its AC, its just not sinusoidal.

Can a transformer operate on triangular AC? Yes, but not as efficiently as on sinusoidal AC.

In D.C supply the transformer is not connected why?

In a DC power supply a transformer is connected. The only time there would be no transformer used would be if the DC voltage wanted was 120 VDC. The transformer in the power supply is connected to 120 VAC on the primary side and the secondary side of the transformer is connected to either a half wave or a full wave diode bridge. The voltage out of the diode bridge will be the same output voltage potential as the transformer's secondary voltage but it will be a DC (Direct Current) potential.Reading the question in another way, transformers are not connected in a DC circuit. The reason being is that the transformer operates on a collapsing magnetic field. This field induces a voltage into the secondary side of the transformer. Since the DC circuit does not operate on the principle of a collapsing field except when the circuit is opened, the transformer would not operate as a transformer should..


Why transformer do not operate with DC?

Transformer works with varying flux. DC won't create it. Only AC produce varying flux.


Why carrier signal are sinusoidal?

It does not have to be. Voltage can be DC, sinusoidal, square wave, triangular wave, etc.


Is IC555 is an ac device or dc device?

it is DC powered, but can generate sawtooth or triangular wave AC if wired up properly. it cannot generate sine wave AC, although with an opamp wave shaping circuit the triangular AC waveform can be reshaped to a rough approximation of a sine wave.


Can a transformer run on a higher-than-zero sine wave?

Well first of all DC does not have a sine wave. DC current is one direction only and would appear as a flat line on a graph. Second no DC doesn't not work on a transformer because it becomes saturated at a constant level. You need oscillating voltages to pass through a transformer.


If a dc voltage of 12v is added to the secondary of step down transformer and rating of transformer is 220 input and 12v output what will be the result from primary of transformer?

Adding a DC voltage to the secondary of a transformer will not have an effect on the primary side, as transformers work on the principle of electromagnetic induction which is based on alternating current. The primary side of the transformer will still operate based on the input AC voltage of 220V. The DC voltage on the secondary side will not be transferred to the primary side.


What is TUF for half wave rectifier?

It indicate how well the input transformer is being utilized. It is given by the ratio of DC output power to the AC power rating of Transformer.


Can you run 12 volt DC adapter equipment with a 12 volt transformer?

No, a 12-volt DC adapter and a 12-volt transformer are typically used with different types of devices. A 12-volt transformer is used to convert AC power to a low-voltage AC output, while a 12-volt DC adapter is used to step down AC power to a low-voltage DC output. If the equipment requires a 12-volt DC input, you should use a 12-volt DC adapter, not a transformer.


Is a transformer used in full wave rectifier?

A full wave rectifier is a component or set of components that change AC waveforms into DC. It is frequently used as part of a power supply circuit and therefore it is often directly adjacent to a transformer. However, a transformer is used to provide a suitable AC voltage and is not part of the rectifier.


Why doesn't an AC appliance operate on DC?

Anything with a transformer in it will not work on DC because the transformer will draw enough current to blow the fuse (or catch fire) because transformers must always have a changing voltage. A simple heater will work on AC or DC. Appliances with most types of motor will only work on AC.


What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full-wave rectifier circuit with a filter capacitor?

25.46V assuming output of transformer is pure sinewave.
