What is Kershaw law?
What is Kershaw law?
Kirchhoff’s circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff.
What is Lawrence Law?
Lawrence Law is a boutique business law firm focused on solving legal issues for businesses and businesspeople. From high-stakes litigation to day-to-day employment law advice and contract drafting, Lawrence Law attorneys bring in-depth experience, professionalism, and responsiveness to matter issue they handle.
What is Grayson law?
In economics, Gresham’s law is a monetary principle stating that “bad money drives out good”. For example, if there are two forms of commodity money in circulation, which are accepted by law as having similar face value, the more valuable commodity will gradually disappear from circulation.
What is F IlB?
A current (I) in a magnetic field ( B) experiences a force ( F) given by the equation F = I l × B or F = IlB sin θ, where l is the length of the wire, represented by a vector pointing in the direction of the current. The direction of the force may be found by a right‐hand rule similar to the one shown in Figure .
Who discovered Lorentz force?
During the 19th century important connections between electricity, magnetism and light were clarified by Hendrik Lorentz. In 1892 he presented his electron theory, which posited that in matter there are charged particles, electrons, that conduct electric current and whose oscillations give rise to light.
Who made Gresham’s law?
economist Henry Dunning Macleod
The expression “Gresham’s Law” dates back only to 1858, when British economist Henry Dunning Macleod (1858, p. 476-8) decided to name the tendency for bad money to drive good money out of circulation after Sir Thomas Gresham (1519-1579).
How does Gresham’s law work?
Gresham’s law says that legally overvalued currency will tend to drive legally undervalued currency out of circulation. Gresham’s law originated as an observation of the effects of metallic currency debasement, but also applies in today’s world of paper and electronic moneys.
What is B in qvB?
The equation is given by F = q v × B or F = qvB sin θ, where q is the charge, B is the magnetic field, v is the velocity, and θ is the angle between the directions of the magnetic field and the velocity; thus, using the definition of the cross product, the definition for the magnetic field is.
What is the Lorentz law used for?
Whenever a moving charged particle is in the presence of a magnetic and electric field the Lorentz force law tells us that the total force from these fields acting on the charged particle is equal to the sum of the electric and magnetic forces.
What is the application of Lorentz force?
Lorentz force, the force acting on moving charged particles in a magnetic field (Figure 1), plays a crucial role in various applications ranging from electronic devices and motors, sensors, imaging to biomedical applications.
