maxwell equations - units

שליחה על ידי yellinb » 20:24 06/05/2007

according to griffith book maxwell equations for vacum and no source are:
rot E = - dB/dt
rot B = 1/e0m0 dE/dt
where e0 is the dialecteric constant and m0 is the premability constant
while in your lecture notes its different (1/c for bothe equations)
why there is a diffrence? how do i soppuse to translate from one method to another?

It is different units of measurements. Griffith uses SI and I am using Gaussian system. In my Physics 2 lectures I am giving a general form which can be reduced to either
