If Co is the capacity of a condenser when the region between the surfaces is

evacuated and C is its capacity when this region is filled with a dielectric, the

of C to C0 is found to be independent of the shape or size of the condenser ...

If Co is the capacity of a condenser when the region between the surfaces is

evacuated and C is its capacity when this region is filled with a dielectric, the

**ratio**of C to C0 is found to be independent of the shape or size of the condenser ...

The emf. induced in a wire of length 1 is E • 1, and since n is a unit vector

perpendicular to E, Eq. (16.31) can be written 2t/\ E' • a, where E' is a vector of

length E but rotated t/2 about the wave normal, i.e., in the direction of B. The

of the ...
