Cu loss means I^2*R loss so it depends on R and I.If we make wire more resistive it means it will increase the value of R so copper loss will be increase.So to concentrate on wire size we can vary the R value and can protect the copper loss.So it is called variable loss.

Types of losse in AC generator?
stray loss copper loss
Which loss in transformer varies significantly with load?
Copper loss varies with the load.
What is signal distortion in transmission lines?
there are some distortion in transmission line : copper loss,dielectric loss,skin effect
Why does the open-circuit test essentially show only excitation losses and not in copper losses?
In an open circuit test full load current does not flow, hence you wont get copper loss.
What are losses of transformer?
Core loss is one of the many fixed losses in a transformer. This means that no matter the loading of the transformer there this loss would be fixed unlike copper loss which depends on the loading of the transformer.
Why iron loss is constant but copper loss is variable in a transformer?
Iron loss it includes the core loss is partically the same at all loads and copper loss the value of cu loss is found from short circuit test
What charge is copper 2 solphide?
Copper II sulphate has variable valency properties, which translates to variable charges.
Is copper metal a independent variable?
Copper metal is a chemical element.
Is copper a borrower or a lender?
Copper loss electrons.
How many types of losses in transformer?
Basically two types: 1. Copper losses:- when the transformer is loaded, current flows in primary and secondary winding, there is loss of electrical energy due to the resistance of the primary winding, and secondary winding and they are called variable losses. These losses depend upon the loading conditions of the transformers. Therefore, these losses are also called as variable losses. 2. Iron losses or core losses:-The losses that occur in the core are known as core losses or iron losses. Two types of iron losses are: > eddy current loss > Hysteresis loss.
In algebra I what is the input variable called?
The input variable is called the independent variable, and the ouput variable is called the dependent variable.
What is the input variable called in algebra?
the input variable is called the independent variable and the output variable is called the dependent variable.
What are copper losses in a transformer?
Copper losses are purely voltage-drop losses (I squared R) caused by the resistance of the windings, as opposed to hysteresis losses and eddy current losses (so-called iron losses), which are magnetic in nature. They are called copper losses whether the winding conductors are made of copper or not, by the way.
Calculate copper losses at 75c?
Copper Loss at 75 C = Copper Loss at Ambient Temperature C * (310/(235+Ambient Temperature C))
The input variable is called the what variable?
The independent variable. The output variable is dependent on this variable's value and so is called the dependent variable.
Types of losse in AC generator?
stray loss copper loss
Output line drawn in circle diagram of induction motor used to find variable losses and is variable loss change with rotor current?
Yes, the output line used to find the losses, usually for smaller machines we take copper losses equal to the iron losses.
