Every time I try to find frequency on this problem I get the same answer - and according to the simulation it is incorrect. Here's a picture of the simulation. Please note: I am just trying to find frequency. I know the other two variables (.6A and 6V ; these are confirmed correct) [PLAIN]http://img854.imageshack.us/img854/100/screenshot20110724at104.png [Broken] Looking at this image, I see only 2 and 1/4 cycles. Frequency is, essentially, cycles per second (1/s) and period is the time it takes to complete a single cycle. Based on the image I attached, I see 2 and 1/4 cycles (9/4) over a time of .5e-6 s. This is the same as dividing (9/4) by (.5e-6). (9/4) / (.5e-6) = 4.5e6 s^(-1) I do not understand where my mistake is.
