Power and electric field equation
WebField intensity (field strength) is a general term that usually means the magnitude of the electric field vector , commonly expressed in volts per meter. At frequencies above 100 MHZ, and particularly above one GHz, power density (P D ) terminology is more often used than field strength. Power density and field intensity are related by equation ... WebIn Coulomb's Law, the distance between charges appears in the equation as 1 / r 2 1/r^2 1 / r 2 1, slash, r, squared. ... The strength of the electric field falls off as 1/r^2. Magnetic poles always exist as pairs, a North and a South. This is called a "dipole", (two poles). The strength of a dipole falls off as 1/r^3.
