Define Ohm's Law
Ohm's Law: Relationship among the potential difference across an electric device and the current that runs by it.
V= I.R
As shown in the figure below, a source at S is sending out a spherical wave: E 1 =(A ×D/r) cos( wt-2πr/ λ) ; where r is the distance to source S. In addition, there is anoth
