FIRST OF ALL MOISTURE CAN MAKE A PROBLEM IF MOISTURE IS GOOD THE CAUSTIC DILUTION CAN MAKE A PROBLEM IF AFTER DEHYDRATION YOUR SAMPLE IS CLEAR IT WILL NOT MAKE A PROBLEM IF IT IS NOT CLEAR THIS MEAN THAT THERE IS CONTIMINATION OF CAUSTIC IT WILL HAZZY AND ONE MORE THING THE CORRISIVE METERIAL FROM THE LINES CAN MAKE TROUBLE AND SOLUBLE WITH OIL AND IT CAN MAKE A PROBLEM ALSO ON RESISTIVITY

What else can I help you with?
What is a controlled variable in an experiment?
controlled variable is the factor that leaved unchanged to investigate any only one factor that has been changed in the other experiment and the effect of not altering this factor.
Experiments that involve two tests that are identical except for one factor?
A controlled experiment involves two tests that are identical except for one factor, which is the independent variable. The effect of the independent variable is the one being tested.
A variable measured in an experiment?
The variable measured in an experiment is called the dependent variable" the outcome factor". In contrast, the independent variable is the experimental factor that is manipulated; the variable who effect is being studied.
Which factor has the greatest effect on the melting point of a crystalline solid?
The factor that has the greatest effect on the melting point of a crystalline solid is the type of bonding among the particles. Heat breaks the bonds that hold the particles together.
In an investigation what name is given to the type of variable that you change?
In an investigation, the variable that you change is called the "independent variable." It is the factor that is manipulated to observe its effect on another variable, known as the dependent variable. The independent variable is crucial for establishing cause-and-effect relationships in experiments.
What is dissipation factor?
Dissipation factor, also known as tan Delta, is a measure of energy lost in a dielectric material when subjected to an alternating electric field. It quantifies the energy dissipated as heat rather than stored as electrical energy. A high dissipation factor indicates higher energy losses and poorer efficiency of the material as a capacitor.
Why capacitance and dissipation factor tests performed on power transformers?
Measuring capacitance means that we are checking the change to the physical parameters of the transformer. i.e. C=AxDielectric constant/4xdxPie (All these variables are physical parameters) by measuring capacitance we can see the quality or change to the insulation of TR winding. Measuring Dissipation factor means to check the level of contamination and moisture in the insulation ,by def. its a measure of loss rate of energy , in transformer whats that means is the amount of resistive portion of the current in the insulation (Ir). definately if there is no contamination and moisture the surface leakage is purely capacitive.

Coulumbs law and effect of medium between two charges?
The addition of a medium or insulator between the two point charges will decrease the coulumb's force between them by a factor named epsilon r which is different for every insulator.the addition of a insulator between the charges will result in the appearance of a factor named epsilon r in the denominator of the mathematical expression of the coulumb force and the value of epsilon r is unity for vacuum but greater than 1 for every kind of insulator
What are applications of schering bridge?
A Schering Bridge is a bridge circuit used for measuring an unknown electrical capacitance and its dissipation factor.
What are the limitations of the potentiometer?
A potentiometer is limited by it value(resistance) , it's wattage ( heat dissipation factor) and it's physical size.
Is there a significant interaction when there is a significant effect for factor A and a significant effect for factor B?
no
When the effect of one factor depends on the presence of another factor outcomes are said to reflect?
When the effect of one factor depends on the presence of another factor, outcomes are said to reflect an interaction effect. This means that the relationship between the two factors is not additive; instead, the impact of one factor changes depending on the level of the other factor.
What are the characteristics of an overhead line insulator?
The insulator has to have the insulation factor of the primary line that is connected to it. It has to have a design that will not allow moisture to pool around it. The design also should include a shape that will make it self cleaning.
What is a factor that has the greatest effect in keeping down the size of a population?
limiting factor
What is a linear factor?
What is a linear factor What is a linear factor A linear factor is defined as a small change here will effect a small change there by a set value or factor.
What is the factor that has the greatest effect in keeping down the size of a population called?
limiting factor
What factor has the same effect on temperature as elevation?
latitude
