WebElectric field is the force experienced by a test charge that has a value of +1 +1. One way to visualize the electric field (this is my mental model): imagined small positive test charge glued to the end of an imaginary stick. (Be sure your imaginary stick doesn't conduct, like … For the electric force, the force-carrier is the photon, which is sort of like a "chunk" … The strength of the electric field falls off as 1/r^2. Magnetic poles always exist as … First, draw a coordinate plane with q0, the body with charge +4 C, as the origin an… WebAn electron accelerated through a potential difference of 1 V is given an energy of 1 eV. It follows that an electron accelerated through 50 V gains 50 eV. A potential difference of 100,000 V (100 kV) gives an electron an energy of 100,000 eV (100 keV), and so on.
