----> ampere's law :
which is to be used while finding magnetic fields inside the enclosed surface. we are allowed to use it to any surface however the surface have to be in such ways that the path must pass through the point and the path must have enough symmetry so that is constant along the large path of it!
----> Biot Savart law : we often use biot savart to find magnetic fields
generated by an electric current carrying wire of radius "r" and since the radius is perpendicular with I we don't worry about messy integration!
thus we left with : dB =( µ_0 Idl) / (4πr^2)
also knowing that l = 2πr helps so we substitute it in! and we eventually end up with : dB =( µ_0 Id2πr) /(4πr^2)
Thus B = µ_0 I / 2πr
Combining Ampere Law to Biot savart.
Thus we can derive Biot savart from ampere by the following:
§ B.dl = µ_0 I (encl)
B § dl = µ_0 I (encl) hence B (2πr) is
B(2πr) = µ_0 I
so B = (µ_0 I) / 2πr

Where will you use ampere circuital law in preference to biot savart law?
Depends on whether a path integral or a normal integral is easier to determine.
What will be the load voltage if load resistance is 10 k ohm and load current is 2 ma?
Ohm's Law: Voltage is equal to current times resistance 0.002 amperes times 10,000 ohms equals 20 volts.
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
How many amps is 20000 watts?
Hi. Power Law or Watt's Law of James Watt tells us that Power P (in watts) = current I (in amperes) X voltage E (in volts) or P=I x E, therefore I=P/E so just divide 2000w by 240v. Thanks.
If you multiply amps times volts the answer will be in units of?
Voltage, measured in volts. <><><> This question is derived from the fundamental relationship between electrical components which is known as Ohms Law: V = I x R where V = voltage (Volts), I = current (Amps) and R= resistance (Ohms).
Can you prove Biot-Savart's law directly?
No, it was found by expirement.

What is the difference between coulomb's law and biot savart law?
According to Coulomb's law, the electrostatic force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of distance between their centers. And Biot Savart's law gives the magnetic field at point due to a small current element. And, according to Biot Savart's law ,the magnitude of magnetic field is directly proportional to the product of current element Idl and Sin theta and inversely proportional to the square of distance between two point charges.
Prove that current can be a source of magnetism?
A classic and ancient experiment is to get a compass, a battery (9volt is fine), and some wire. Notice that the compass changes when the circuit is closed (wire connected to the two terminals). You can also see that the compass gets affected less when it is far from the wire versus next to it. If your interested in the math behind the experiment, you may want to do some research on the Biot-Savart Law. The Biot-Savart law describe the magnetis field when the current is constant, or not time-varying. A more general form of the equation is called Ampere's Law, and the more general case of that is Maxwell's equations.
What is the differential form of Biot and Savart law?
Hi this is it : dB=m0I/4pi (dl x r) / |r3|, I hope this works for you.you can take r unitary if you change |r3| by |r2| and make cross product alotmuch simpleThis is took of my class of Electrodynamics 2
Magnetic field due to a current through a circular loop?
The magnetic field due to a constant current through a circular loop is the same shape, outside the loop, as the field due to a bar magnet. At the centre of the loop the field can be found, using the Biot-Savart Law, to be (Equation 1: URL in related links), where ?0 is the permeability of free space, I is the current through the loop, R is the radius of the loop and z-hat is a unit vector perpendicular to the plane of the loop. The field on the axis of the loop can be found, again using the Biot-Savart Law, to be (Equation 2: URL in related links), where z is the distance from the centre of the loop along its axis and all other symbols have the same meaning as in the previous equation.
What ia bragg's law with derivation?

What is derivation of law of demand?
Law of demand is the higher the price the lower of goods demand for
Similarities and differences between Biot-savart law and coulombs law?
similarities:1. field at any point vary inversely at the square of the distance.2. both obey superposition principle3. the magnetic fields linear in the source just as electric field.dissimilarities:1. E is produced by a scalar source (q) where as B is produce by vector source (Idl)2. E is acting along the displacement vector where as B acts perpendicular to Ixr.3. E is not depended of θ where as B depends upon θ.
What is Newton's derivation of Kepler's third law an example of?
Deductive reasoning.
Meaning of bio-savart's law?
Meaning is to quantitatively analyze the magnetic field of a steady line current a distance r from it. Make sure to use that appropriate coordinates.
How do you prove benford's law?
Benford's law is obtained as maximum entropy distribution of balls in boxes under the assumption that the number of balls in a box can be 1,2,3....9. For derivation see Oded Kafri "entropy principle in direct derivation of Benford's law" at arxive (2009) .
