What part in a circuit that produces potential difference?
The potential difference is provided by the power source, which can be a battery or some form of electric generator. Inside the source, electric charges are raised up a potential gradient, and they then give up their energy as they travel down the potential gradient in the circuit that is being supplied with energy.
What is an EPD?
EPD stands for Expected Progeny Difference. This is a set of variable that give you an idea how well the offspring of this animal will preform for you.
What is practical voltage source?
in case of ideal voltage source we consider the internal resistance to be zero.but in practical,every battery has some internal resistance then if you connect a load resistance across the terminals of that source,the net potential difference's across the voltage source will be a function of external resistance connects it won't give constant voltage across it's terminals.

Difference between absorption costing and marginal costing calicut uviversity?
The difference between marginal and absorption costing is that when preparing a statement based on marginal costing, you would subtract all variable costs, production or otherwise, from the sales revenue, to give the contribution, from which you subtract all fixed costs (production and non-production) to give profit made.Using absorption costing however, you subtract production costs (this will include both variable and fixed production costs) only from sales to give you the gross profit, from which you then subtract all non-production costs (fixed or variable) to give net profit.The final profit using both methods is always the same.
Difference of descriptive statistics and inferential statistics?
Descriptive statistics label, name, or give information about a variable. Inferential stats are inferred from a smaller data set to be valid for the whole population.
What is difference between voltage and emf?
An electromotive force (e.m.f.) is the open-circuit, or no-load, potential difference provided by a source -such as a battery or generator. For a closed circuit, an e.m.f. is the sum of the voltage-drops around any closed loop, including the internal voltage drop of the source.A potential difference (voltage) can exist across any circuit component. For example, the fact that current is flowing through each of several resistors in a series circuit means that there must be an individual potential difference across each of those resistors (which we also term 'voltage drop').An electromotive force is the name we give to the open-circuit potential difference provided by a generator, battery, etc. For example, the open circuit potential difference of a battery would be its electromotive force.So, if we use a series resistive circuit as an example, the battery would provide the electromotive force, while voltage drops would then appear across its internal resistance, and across each of the resistances. The magnitude of the electromotive force is then equal (but acting in the opposite sense) to the sum of the voltage drops, including the internal voltage drop.Many textbooks use the symbol, E, to represent an electromotive force, and V to represent potential difference. So, Kirchhoff's Voltage Law, for example, will often be seen written as: E = V1 + V2 + V3 + etc.
How do you find the voltage at a point in a circuit with respect to a negative voltage?
First of all, 'voltage' means potential difference -and you cannot have a potential difference 'at a point'. Similarly, you cannot have a 'negative' potential difference, so it doesn't make sense to talk about a 'negative voltage'.Your question, therefore, should read: 'How do you find the potential at a point in a circuit with respect to a negative potential?'The answer is that you simply connect a voltmeter between the two points. The reading will give you the value of the potential. If it reads upscale, then it'll be positive; if it reads downscale, then it will be negative (i.e. even more negative tan the reference potential).
What are the independent and depent variables?
You can tell which is the independent variable and which is the dependent variable by changing the equation into an "if/then" statement. Example: y = 3x In this example, x is the independent variable and y is the dependent variable. If you give me x, I will tell you y. If x = 1, then y = 3 If x = 2, then y = 6 So you give me the independent variable, and then I will be able to determine the dependent variable.
