Primary markets can not function well without secondary markets
The primary function of a bottle is to contain liquids, such as water or beverages. The secondary function of a bottle is to provide a means for easy storage, transport, and consumption of the liquid it holds.
Primary market can not function well without secondary market because they are interrelated with each other as well as interdependent.
Primary function: to sit on. Secondary functions: to stand on; use a shield against lions; swing around wildly
To electrically isolate the secondary circuit from the primary circuit, without changing the voltage.
The function of an isolation transformer is to electrically-isolate the secondary circuit from the primary circuit, without changing the voltage levels. So, its secondary voltage will be the same as the primary voltage.
When the secondary of a transformer is opened, there is no longer any load on the transformer. There will be some current flowing in the primary winding, which is needed to induce the voltage in the secondary. This primary current is referred to as the "no load" current, and is indicative of the core losses in the transformer.
I am assuming the question is about the power / distribution transformer and not the current transformer. The primary current is a function of load connected on secondary. With the open secondary, there is no load, no current, it is open circuit. Hence no primary current. However there is always some small amount of no load current in the primary winding.
Primary Means, it is individual there is no dependence, But Secondary will allays depends on Primary, If you want to do Secondary, you should complete primary first, There is no precondition to primary, but for Secondary Primary is the Precondition, first you should do primary, then only you are able to do secondary.
