Hi i'm doing a report on microwave ovens and we have to include relevant equations in our reports. I've seen this on: http://www.lsbu.ac.uk/water/microwave.html and i've tried to use it to solve for Emax since (i think) i know the others, e.g. 4000v is applied across the magnetron so im guessing this is the E, the angular frequency is 2pi x 2450x10^6, and t is the time you leave the microwave oven on for i think? Anyway it doesn't work and we have never studied this equation in class so im very confused. Any help would be appreciated and any other relevant equations for microwave ovens would be great.
