Fortunately, it is possible to define a quantity, called the electric field, which is independent of the test charge. It only depends on the configuration of the source charges, and once found, …
Lorentz force - Wikipedia
Lorentz force (per unit 3-volume) f on a continuous charge distribution (charge density ρ) in motion. The 3-current density J corresponds to the motion of the charge element dq in volume …

2025年2月28日 · F = electric force on the charge (N) q = magnitude of the charge (C) Electric field strength is a vector quantity. Its direction is defined in terms of the direction a small positive …
Lorentz force - Simple English Wikipedia, the free encyclopedia
F = qE (electric force) If the charge is positive, the direction of the electric force is equal to direction of electric field. F = qv*B (magnetic force) The direction of the magnetic force is given …
Electric field - Boston University
The value of the acceleration can be found by drawing a free-body diagram (one force, F = qE) and applying Newton's second law. This says: qE = ma, so the acceleration is a = qE / m.
Electric Field - Isaac Physics
In the absence of an electromotive force (e.m.f) provided by a power supply or a changing magnetic field inside the conductor, free charges will flow inside conductors. This happens …
Electric Charge Calculations - Math is Fun
The force (F) felt by a charged particle in an electric field is calculated using: F = qE. F = Force on the charged particle (N) q = the object's charge in Coulombs (C) E = strength of the electric …

Electric potential | Definition, Facts, & Units | Britannica
The electric force F exerted by the field on the positive charge is F = qE. To move the charge from plate A to plate B, an equal and opposite force (F′ = −qE) must be applied. The electric …
