If the primary winding of the transformer in the power supply opens what will you observe in the rectified output?

There would be no rectified output. The transformer primary has to be closed to induce a current into the secondary winding. At this point of the secondary the voltage is still AC. This voltage is then applied to the rectification bridge to change it to DC. So you can see how no voltage on the primary, the same as the unit being unplugged, affects the output voltage.

The primary winding in a transformer is connected to the what?
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
What is LV winding of a transformer?
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.
What is winding transformer?
A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
The primary winding in a transformer is connected to the what?
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
What is LV winding of a transformer?
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.

What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
Does the primary winding VA equal the secondary winding VA when a transformer is loaded?
no becouse transformer function depends on no of coil in primary and secondry coil
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
What type of transformer is used to prevent electrical noise from passing from the primary winding to the secondary winding?
Shielded transformer
Is there more current in the primary or secondary winding of a transformer?
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.
What are the primary winding and secondary winding of a transformer?
The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. The terms, 'primary' and 'secondary' are unrelated to voltage levels.
How can you distinguish the primary from secondaty side on a transformer?
Whichever winding is connected to the supply is the primary winding; whichever winding is connected to the load is the secondary winding.
Difference between input and output transformer?
The 'input' side of a transformer is called its 'primary' side, whereas the 'output' side is termed its 'secondary' side. The ratio of its secondary to primary voltage is equal to the ratio of the number of turns in the secondary windings to the number of turns in the primary winding. So if, for example, a transformer's secondary winding has twice as many turns as its primary winding, then the secondary winding will produce twice the voltage applied to the primary winding.
What is the term for the transformer winding to which the load is connected?
The load is connected to the transformer's secondarywinding, while the primary winding is connected to the supply. The terms, 'primary' and 'secondary', do NOT relate to voltage levels.
